Description
Apparatus and method for conveying into and out of a hollow The present invention relates to an apparatus and a method for filling a hollow with solid con-veyed material or for removing solid conveyed material from a hollow.
In surface mining, natural resources such as ores, stone, sand, gravel or coal are extracted from layers close to the surface. Mining is carried out with excavators or bucket wheel exca-vators, and by blasting, milling, etc. The material extracted is often removed from the mining site for further processing by belt conveyor systems. Surface mines can also reach great depths, which can make removal with belt conveyor systems complex, because the belt con-veyor system often has to be moved and adjusted in length.
.. Conventional belt conveyor systems with a driven, endless conveyor belt, which is deflected via deflection rollers at both ends of the belt conveyor system, can be used as conveying de-vices for conveying the material to be conveyed. A plurality of support rollers are generally provided between the deflection rollers in order to support the conveyor belt, in particular the run in which the material is conveyed. Conveying devices are also known with a conveyor belt on which a plurality of support rollers are arranged, which are distributed over the length and which roll on fixed track ropes. Examples of this can be found in EP 2 460 744 B1 or EP

Examples of this can be found in EP 2 460 744 B1 or EP
2 030 919 B1. Furthermore, a known aerial cableway designed as a reversible aerial tram-way for transporting conveyed material, such as bulk material, can also be used as the con-veying device. A material bucket for receiving the material to be conveyed is arranged on a hanger of the reversible aerial tramway. The hanger is suspended from a running gear with a number of support rollers on a track rope (or a plurality of track ropes) and is usually moved back and forth between two stations with a pull cable attached to the running gear.
Surface mining sometimes also leaves very spacious and/or deep hollows in the landscape.
It is often a desire or a requirement to backfill such hollows with material after the surface mine has been abandoned, for example because the deposit has been exhausted.
Hollows to be filled can of course also be created in other ways than through the extraction of natural resources. Hollows are often filled with conveying devices in order to transport the filling ma-terial to the right place. This is also complex because the conveying device often has to be relocated and its length adjusted. The above-mentioned conveying devices can also be used for this purpose.
It is an object of the present invention to provide an apparatus and a method that permit flexi-ble, simple removal of solid conveyed material from a hollow or flexible, simple filling of a hol-low with solid conveyed material.
According to the invention, this object is achieved with at least one track rope which is fixed between two anchor points over the hollow and which sags between two support points in Date Recue/Date Received 2021-01-08 the shape of a catenary, wherein a conveying device for conveying the conveyed material is arranged suspended from the at least one track rope, wherein the anchor points are each ar-ranged above a desired filling height in the region of the respective anchor point and a track rope length of the at least one track rope between the two support points is longer than a conveying length of the conveying device between the two support points, and wherein at at least one anchor point there is provided a rope adjustment device for adjusting the track ropes between the two support points. This means that the track rope can be pulled at cer-tain times in order to shorten the track rope length between the two support points while at the same time the at least one track rope with the conveying device suspended therefrom is moved upwards, or the track rope can be slackened at certain times in order to extend the track rope length between the two support points while at the same time the at least one track rope with the conveying device suspended therefrom is moved downwards.
In this way, the sag of the track rope in the hollow can be adapted to the hollow, so that the conveying device can always be kept at the required or desired distance from the hollow base. A reloca-tion of the conveying device or of anchor points or of support points is therefore no longer necessary, which considerably simplifies the effort required to convey into or out of the hol-low.
A transfer station for loading onto the conveying device or for unloading from the conveying device is preferably provided in the region of an anchor point and the rope adjustment device is provided at the opposite anchor point. In this way, the end of the track rope on which the conveying device is not suspended can be adjusted, so that an adjustment of the suspension points of the conveying device on the track rope that may otherwise be necessary can be dispensed with. This simplifies the use of the apparatus.
In order to be able to make the conveyance of conveyed material into the hollow more flexi-ble, a distribution conveying device can be arranged suspended from the at least one track rope in the region of an end of the conveying device in the hollow, wherein the conveying de-vice conveys the conveyed material onto the distribution conveying device. By appropriately designing the distribution conveying device, the distribution of conveyed material in the hol-low can easily be adapted to the respective requirements and circumstances. It is particularly advantageous if the distribution conveying device is designed as a distribution belt conveyor system that can be operated in both conveying directions. In this way, conveyed material can be unloaded at two different points in the hollow in a simple manner, which supports the fur-ther distribution of the conveyed material in the hollow.
In the following, the present invention is described in greater detail with reference to Fig. 1 to 6 which, by way of example, show schematic and non-limiting advantageous embodiments of the invention. In the drawings:
Date Recue/Date Received 2021-01-08 Fig. 1 is a cross-section through a hollow with a track rope fixed over it, Fig. 2 is an embodiment of a conveying device for conveying into and/or out of the hol-low, Fig. 3 shows an end of the conveying device in the region of an anchor point of the track rope, Fig. 4 shows an end of the conveying device in the hollow, Fig. 5 shows an end of the conveying device in the hollow with a distribution conveying device, and Fig. 6 shows an anchor point with an embodiment of a rope adjustment device.
The invention is described below primarily using the example of filling a hollow with conveyed material, in particular bulk material. The conveyed material is removed from a hollow in an analogous manner in the opposite direction.
Fig. 1 is a cross-section through a hollow 1, which can typically reach a depth in the range of a few tens of meters to a few hundred meters, shallower or even deeper hollows being of .. course also conceivable. The width and length, or approximately a diameter, of the hollow 1 can be in the range of a few hundred meters, with smaller and larger dimensions also being conceivable. The hollow 1 has a hollow base 2, from which the hollow slope 3 extends up-wards all around with a slope angle. Of course, the hollow 1 does not have to be symmet-rical, nor does it have to have the same slope angle on all sides. The hollow slope 3 can also be created in the form of steps. The shape and the dimensions of the hollow 1 are ultimately secondary to the invention. For filling, conveyed material is transported onto the hollow base 2 in order to fill the hollow 1, whereby the hollow base 2 rises. Conversely, conveyed material obtained in the hollow 1 is removed from the hollow base 2, whereby the hollow base 2 can sink further.
At least one track rope4 is fixed over the hollow 2 between two anchor points Al, A2. A plu-rality of track ropes4 can also be fixed, wherein the number of track ropes required naturally depends on the span and the load to be supported. The at least one track rope 4 is sus-pended over the hollow 1 between two support points SP1, SP2 in the shape of a catenary, which results in a track rope length IT as the length of the catenary between the two support points SP1, SP2. The catenary results as a function of the span, the arrangement of the sup-port points SP1, SP2 and the load on the at least one track rope 4. A support point SP1, SP2 can be an anchor point Al, A2, for example the anchor point A2 in Fig. 1, or a support for the track rope 4, for example on a support pole 5, for example on a support pole 5 in Fig. 1. The track rope length IT between the two support points SP1, SP2 does not have to correspond to the actual length of the at least one track rope 4 between the two anchor points Al, A2, de-pending on the specific design. In an advantageous embodiment, the two support points SP1, SP2 coincide with the anchor points Al, A2.

At least one track rope4 is fixed over the hollow 2 between two anchor points Al, A2. A plu-rality of track ropes4 can also be fixed, wherein the number of track ropes required naturally depends on the span and the load to be supported. The at least one track rope 4 is sus-pended over the hollow 1 between two support points SP1, SP2 in the shape of a catenary, which results in a track rope length IT as the length of the catenary between the two support points SP1, SP2. The catenary results as a function of the span, the arrangement of the sup-port points SP1, SP2 and the load on the at least one track rope 4. A support point SP1, SP2 can be an anchor point Al, A2, for example the anchor point A2 in Fig. 1, or a support for the track rope 4, for example on a support pole 5, for example on a support pole 5 in Fig. 1. The track rope length IT between the two support points SP1, SP2 does not have to correspond to the actual length of the at least one track rope 4 between the two anchor points Al, A2, de-pending on the specific design. In an advantageous embodiment, the two support points SP1, SP2 coincide with the anchor points Al, A2.
- 3 -Date Recue/Date Received 2021-01-08 If the topology of the hollow 1 and/or the arrangement of the anchor points Al, A2 requires it, a support pole 5 (or a plurality of support poles) for the at least one track rope 4 can also be provided at a suitable location.
The support points SP1, SP2 are preferably arranged above the desired filling height hv in the region of the respective support point SP1, SP2, i.e. at a higher level.
The filling height hv is the level of the hollow base 2 after filling. In the case of mining, the filling height hv corre-sponds to the initial height, i.e. the hollow base 2 at which mining begins.
In the case of in-clined filling, however, one support point SP1, SP2 could, for example, be arranged lower than the other support point SP1, SP2 and also lower than the filling height hv in the region of the other support point SP1, SP2, although the lower support point SP1 would nevertheless preferably be higher than the filling height hv in the region of the lower-lying support point SP1. It can thus be achieved that the at least one track rope 4 always runs above the respec-tive hollow base 2 without providing any further supports. Depending on the topology of the hollow, it is therefore not absolutely necessary to strive for horizontal filling.
Depending on the track rope length IT, the track rope 4 sags to a greater or lesser extent be-tween the anchor points Al, A2 and there is maximum sag. An upper tensioning position S1 is shown in Fig. 1, in which the track rope 4 sags only slightly and in particular runs above the filling height hv. In a lower tensioning position S2, the track rope length IT is greater and the track rope 4 sags to a greater extent, in particular just above the hollow base 2, usually in the range from a few meters to a few tens of meters.
A conveying device 10 is suspended from the at least one track rope 4, which is explained by way of example with reference to Fig. 2. In this embodiment a total of four track ropes 4 are fixed next to one another and are at least approximately parallel. A first load-bearing struc-ture 11 is suspended from the track rope 4 at a first height and a second load-bearing struc-.. ture 12 at a second height. Of course, a plurality of such load-bearing structures 11, 12 are arranged distributed at certain intervals along the length of the belt conveyor system 10 along the track rope 4. In the embodiment shown, the first load-bearing structure 11 is de-signed as a U-shaped frame which is attached to the track ropes, for example by means of a clamp connection. The second load-bearing structure 12 is also designed as a frame which .. is attached to rods or cables, which in turn are attached to the track ropes 4, for example again by means of a clamp connection. Two guide elements 13', 13", 14', 14"
are arranged next to one another on the load-bearing structures 11, 12 in the direction of the longitudinal extent of the conveying device 10. The guide elements 13', 13", 14', 14" are thus also ar-ranged in pairs at different heights. A guide element 13', 13", 14', 14" can be a cable, a rod, a pipe, a rail or the like, preferably a cable. The distance between the pairs of guide elements gives the track width for support rollers 15', 15", which are arranged on both sides of an end-less, revolving conveyor belt 16 of the conveying device 10. For this purpose, cross struts 17
The support points SP1, SP2 are preferably arranged above the desired filling height hv in the region of the respective support point SP1, SP2, i.e. at a higher level.
The filling height hv is the level of the hollow base 2 after filling. In the case of mining, the filling height hv corre-sponds to the initial height, i.e. the hollow base 2 at which mining begins.
In the case of in-clined filling, however, one support point SP1, SP2 could, for example, be arranged lower than the other support point SP1, SP2 and also lower than the filling height hv in the region of the other support point SP1, SP2, although the lower support point SP1 would nevertheless preferably be higher than the filling height hv in the region of the lower-lying support point SP1. It can thus be achieved that the at least one track rope 4 always runs above the respec-tive hollow base 2 without providing any further supports. Depending on the topology of the hollow, it is therefore not absolutely necessary to strive for horizontal filling.

An upper tensioning position S1 is shown in Fig. 1, in which the track rope 4 sags only slightly and in particular runs above the filling height hv. In a lower tensioning position S2, the track rope length IT is greater and the track rope 4 sags to a greater extent, in particular just above the hollow base 2, usually in the range from a few meters to a few tens of meters.
A conveying device 10 is suspended from the at least one track rope 4, which is explained by way of example with reference to Fig. 2. In this embodiment a total of four track ropes 4 are fixed next to one another and are at least approximately parallel. A first load-bearing struc-ture 11 is suspended from the track rope 4 at a first height and a second load-bearing struc-.. ture 12 at a second height. Of course, a plurality of such load-bearing structures 11, 12 are arranged distributed at certain intervals along the length of the belt conveyor system 10 along the track rope 4. In the embodiment shown, the first load-bearing structure 11 is de-signed as a U-shaped frame which is attached to the track ropes, for example by means of a clamp connection. The second load-bearing structure 12 is also designed as a frame which .. is attached to rods or cables, which in turn are attached to the track ropes 4, for example again by means of a clamp connection. Two guide elements 13', 13", 14', 14"
are arranged next to one another on the load-bearing structures 11, 12 in the direction of the longitudinal extent of the conveying device 10. The guide elements 13', 13", 14', 14" are thus also ar-ranged in pairs at different heights. A guide element 13', 13", 14', 14" can be a cable, a rod, a pipe, a rail or the like, preferably a cable. The distance between the pairs of guide elements gives the track width for support rollers 15', 15", which are arranged on both sides of an end-less, revolving conveyor belt 16 of the conveying device 10. For this purpose, cross struts 17
- 4 -Date Recue/Date Received 2021-01-08 are arranged distributed in the longitudinal direction on the conveyor belt 16, for example by a screw or clamp connection, which protrude over the width of the conveyor belt 16 and at the axial ends of which the support rollers 15', 15" are rotatably mounted. If there are several guide elements 13', 13", 14', 14" on each side of the conveyor belt 16, support rollers 15', .. 15" with different track widths can also be provided on the conveyor belt 16, as in Fig. 2, which then roll on different guide elements 13', 13", 14', 14". At the lateral ends of the con-veyor belt 16, side walls 18', 18" can also be arranged in order to form a U-shaped recepta-cle for the conveyed material on the conveyor belt 16. Distributed in the longitudinal direction of the conveyor belt 16, transverse walls can also be arranged between the two side walls 18', 18" in order to form individual receiving portions, which can facilitate the transport of conveyed material, in particular in sections of the conveyor belt 16 with an incline. The sup-port rollers 15', 15" roll on the respectively assigned guide element 13', 13", 14', 14". The conveyor belt 16 revolve on deflection rollers 19 (see Fig. 3) at the respective ends of the conveying device 10. At least one deflection roller 19 can be driven in order to drive the con-veyor belt 16. This type of conveying device 10 is well known, which is why no further details need to be discussed here.
However, the conveying device 10 can also be designed differently. For example, on the at least one track rope 4, rotatably mounted support rollers distributed in the longitudinal direc-tion can be suspended, on which the conveyor belt 16 is supported. The support rollers can also be arranged on load-bearing structures, which in turn are attached to the track rope 4.
The conveying device 10 would thus be designed in the form of a classic belt conveyor sys-tem. Likewise, the conveying device 10 can be designed as a well-known reversible aerial tramway, with a material bucket which is suspended from a hanger with a number of support rollers on the at least one track rope 4, or a guide element suspended therefrom, and which can be moved back and forth thereon. The hanger with the material bucket can have its own actuator or is moved with a pull rope which is attached to the hanger.
In the region of an end of the conveying device 10, a transfer station U is arranged, which is arranged in the region of an anchor point Al, as shown in Fig. 3. In the transfer station U, ei-ther the conveyed material is loaded into the conveying device 10 (when backfilling) or con-veyed material is unloaded from the conveying device 10 (when excavating or mining). For loading, the conveyed material can for example be placed on the conveyor belt 16 or filled into a material bucket. For unloading, the conveyed material can be removed from the con-veyor belt, for example, or emptied from a material bucket. The way in which the transfer sta-tion U and the loading or unloading are exactly implemented is irrelevant to the invention.
This one end of the belt conveyor system 10 in the region of the transfer station U is thus also arranged above the desired filling height hv in the region of the anchor point Al or in the region of the transfer station U. An actuator 20 for the deflection roller 19 is also indicated in

It is also indicated that support rollers 21 can also be arranged in the region of the transfer station U, for example on a support pole 5 in order to guide a conveyor belt 16 in a targeted manner, for example in a section horizontally, in order to facilitate the handling of the conveyed material at the transfer station U.
Of course, the belt conveyor system 10 could also extend beyond the anchor point Al, de-pending on the arrangement of the transfer station U or the topology of the environment. In this case, for example, corresponding guide elements, also arranged in a stationary manner, on which the support rollers 15', 15" of the conveyor belt 16 roll, could also be arranged in the region of the transfer station U. For this purpose, a suitable transfer, known per se, of the support rollers 15', 15" of the conveyor belt 16 from the guide elements 13', 13", 14', 14" of the conveying device 10 to the guide elements in the region of the transfer station U could be provided.
In the case of a reversible aerial tramway as the conveying device 10, the transfer station U
can be provided, for example, in a cableway station into which the material bucket enters.
The transfer station U, and also the anchor point Al at the end of the conveying device 10 in the region of the transfer station U, can, however, also be provided away from the actual hol-low 1. In this case, the conveying device 10 can also extend further beyond the region of the hollow 1. A configuration is therefore also conceivable in which the anchor points Al, A2 are provided in the region of the hollow 1, but the conveying device 10 extends beyond an an-chor point Al.
The conveying length IF of the conveying device 10 extending along the at least one track rope 4 between the two support points SP1, SP2 is shorter according to the invention than the track rope length IT between the two support points SP1, SP2. The conveying length IF of the conveying device 10 between the two support points SP1, SP2 is preferably in the range of 20 to 80% of the track rope length IT between the two support points SP1, SP2.
In Fig. 4, the other end of the conveying device 10 suspended from the track rope 4 is shown. Since the track rope length IT between the two support points SP1, 5P2 is longer than the conveying length IF, this other end of the conveying device 10 ends between the two support points SP1, 5P2, preferably in a region of the hollow base 2 that is currently being .. backfilled or mined. In a possible advantageous embodiment, the conveying device 10 ends in the region of the maximum sag of the at least one track rope 4.
The deflection roller 22 at this end of the belt conveyor system 10 is also arranged sus-pended from the track ropes 4. For this purpose, a suitable load-bearing structure 23 for the deflection roller 22 can be provided on the at least one track rope 4. The track rope 4 ex-tends beyond the end of the belt conveyor system 10 to the support point 5P2 and anchor point A2, which can coincide (as in Fig. 1). The conveyed material 6 conveyed with the
Of course, the belt conveyor system 10 could also extend beyond the anchor point Al, de-pending on the arrangement of the transfer station U or the topology of the environment. In this case, for example, corresponding guide elements, also arranged in a stationary manner, on which the support rollers 15', 15" of the conveyor belt 16 roll, could also be arranged in the region of the transfer station U.

In the case of a reversible aerial tramway as the conveying device 10, the transfer station U
can be provided, for example, in a cableway station into which the material bucket enters.
The transfer station U, and also the anchor point Al at the end of the conveying device 10 in the region of the transfer station U, can, however, also be provided away from the actual hol-low 1. In this case, the conveying device 10 can also extend further beyond the region of the hollow 1. A configuration is therefore also conceivable in which the anchor points Al, A2 are provided in the region of the hollow 1, but the conveying device 10 extends beyond an an-chor point Al.
The conveying length IF of the conveying device 10 extending along the at least one track rope 4 between the two support points SP1, SP2 is shorter according to the invention than the track rope length IT between the two support points SP1, SP2. The conveying length IF of the conveying device 10 between the two support points SP1, SP2 is preferably in the range of 20 to 80% of the track rope length IT between the two support points SP1, SP2.
In Fig. 4, the other end of the conveying device 10 suspended from the track rope 4 is shown. Since the track rope length IT between the two support points SP1, 5P2 is longer than the conveying length IF, this other end of the conveying device 10 ends between the two support points SP1, 5P2, preferably in a region of the hollow base 2 that is currently being .. backfilled or mined. In a possible advantageous embodiment, the conveying device 10 ends in the region of the maximum sag of the at least one track rope 4.
The deflection roller 22 at this end of the belt conveyor system 10 is also arranged sus-pended from the track ropes 4. For this purpose, a suitable load-bearing structure 23 for the deflection roller 22 can be provided on the at least one track rope 4. The track rope 4 ex-tends beyond the end of the belt conveyor system 10 to the support point 5P2 and anchor point A2, which can coincide (as in Fig. 1). The conveyed material 6 conveyed with the
- 6 -Date Recue/Date Received 2021-01-08 conveying device 10 into the hollow 1 is deposited on the hollow base 2 in the region of the end of the conveying device 10, for example in the form of a conical pile 24, as in the draw-ings. From there, the conveyed material 6 can be distributed on the hollow base 2, for exam-ple by means of further belt conveyor systems, an excavator, a bulldozer, or the like.
To fill a hollow 1 with conveyed material 6, the following procedure should now be followed.
At the beginning of filling, the track rope 4 is in the lower tensioning position S2, i.e. the track rope 4 is so long that it sags sufficiently far to the hollow base 2, wherein it should of course be avoided that the conveying device 10 suspended from the track rope 4 touches the hollow base 2. The conveying device 10 is preferably located a few meters or a few tens of meters above the hollow base 2. Conveyed material 6 is conveyed with the conveying device 10 into the hollow 1 and distributed there on the hollow base 2. This increases the level of the hollow base 2. If the distance between the conveying device 10 and the hollow base 2 gets too small, the track rope 4 is pulled at at least one of the anchor points Al, A2 in order to shorten the track rope length IT between the support points SP1, SP2. When this happens can be .. freely selected and also depends on the distribution system of the conveyed material 6 in the hollow 1. Thereby, the track rope 4 with the conveying device 10 attached thereto moves up-wards at the same time. This is repeated until the hollow 1 is completely filled and the track rope 4 is in the upper tensioning position S1 (Fig. 1). Thereafter, the track rope 4 and the conveying device 10 can also be dismantled if necessary.
It is advantageous if the track rope 4 is pulled at the anchor point A2 opposite the conveying device 10 (in Fig. 1). In this case, the conveying device 10 simply moves upwards without having to alter anything in the suspension of the conveying device 10 on the at least one track rope 4. Since the track rope length IT between the two support points SP1, 5P2 is short-ened, only the end of the conveying device 10 lying in the region of the hollow 1 moves in the .. direction of the anchor point A2.
However, it is also possible to pull the track rope 4 at the anchor point Al (in Fig. 1) on the side of the conveying device 10. In this case, however, the suspension of the conveying de-vice 10 would usually also have to be adjusted (provided that it is not suspended in a floating manner), since the suspension points of the conveying device 10 on the track rope 4 would also be displaced with the track rope 4 in the direction of the anchor point Al.
However, it is also possible to pull the track rope 4 at both anchor points Al, A2 at the same time.
In the case of mining, the process is of course exactly the reverse. It begins in the upper ten-sioning position S1 and the extracted material is conveyed away from the hollow base 2 with the conveying device 10. If the distance between the conveying device 10 and the hollow base 2 gets too great, the track rope 4 is slackened at at least one anchor point Al, A2 in

Conveyed material 6 is conveyed with the conveying device 10 into the hollow 1 and distributed there on the hollow base 2. This increases the level of the hollow base 2. If the distance between the conveying device 10 and the hollow base 2 gets too small, the track rope 4 is pulled at at least one of the anchor points Al, A2 in order to shorten the track rope length IT between the support points SP1, SP2.

Thereby, the track rope 4 with the conveying device 10 attached thereto moves up-wards at the same time. This is repeated until the hollow 1 is completely filled and the track rope 4 is in the upper tensioning position S1 (Fig. 1). Thereafter, the track rope 4 and the conveying device 10 can also be dismantled if necessary.
It is advantageous if the track rope 4 is pulled at the anchor point A2 opposite the conveying device 10 (in Fig. 1). In this case, the conveying device 10 simply moves upwards without having to alter anything in the suspension of the conveying device 10 on the at least one track rope 4. Since the track rope length IT between the two support points SP1, 5P2 is short-ened, only the end of the conveying device 10 lying in the region of the hollow 1 moves in the .. direction of the anchor point A2.
However, it is also possible to pull the track rope 4 at the anchor point Al (in Fig. 1) on the side of the conveying device 10. In this case, however, the suspension of the conveying de-vice 10 would usually also have to be adjusted (provided that it is not suspended in a floating manner), since the suspension points of the conveying device 10 on the track rope 4 would also be displaced with the track rope 4 in the direction of the anchor point Al.

Thereby, the track rope 4 with the conveying de-vice 10 attached thereto moves downwards. This is repeated until the mining is finished.
Here, too, the adjustment of the track rope length IT can take place at each of the anchor points Al, A2 or at both at the same time.
The conveying length IF does not have to be altered, nor does the position of the anchor points Al, A2 or the support points SP1, SP2, which considerably simplifies the realization of the backfilling or mining. As a result of the tensioning or slackening of the track rope 4 during this process, only the end of the conveying device 10 displaces slightly to and fro in the re-gion of the hollow base 2, but this is irrelevant for the realization of the backfilling or mining.
It is also evident from this that the conveying device 10 suspended from the at least one track rope 4 can also be designed differently than described with reference to the specific embodiment, for example with support rollers on which the conveyor belt is supported or with an reversible aerial tramway, since this is irrelevant to the invention.
The at least one track rope 4 is preferably fixedly fixed at one of the two anchor points Al, A2, with the result that the track rope length IT is altered at the other anchor point Al, A2.
This simplifies the design and handling of the system. But it is of course conceivable to make the track rope length IT of the track rope 4 alterable at both anchor points Al, A2.
In Fig. 5, a particularly advantageous embodiment for filling in the region of the hollow base 2 .. is shown. In the region of the end of the conveying device 10 in the hollow 1, a distribution conveying device 25 is arranged suspended from the at least one track rope 4.
The convey-ing device 10 conveys the conveyed material 6 onto the distribution conveying device 25 and is conveyed from there into the hollow 1. In the illustrated embodiment, the distribution con-veying device 25 is designed as a distribution belt conveyor system, other configurations also being conceivable.
In the embodiment of the distribution conveying device 25 according to Fig. 5 as a distribu-tion belt conveyor system, the distribution conveying device 25 has two deflection rollers 26, 27 around which an endless distribution conveyor belt 28 revolves. At least one deflection roller 26, 27 is driven by a drive 29. In this example, the distribution conveying device 25 is designed with support rollers 30 on which the conveying run of the distribution conveyor belt 28 is supported. For the support rollers 30, load-bearing structures 31 are provided, which are arranged on the at least one track rope 4. Corresponding load-bearing structures 32, which are also arranged on the track rope 4, are also provided for the deflection rollers 26, 27. The distribution conveying device 25 could, however, be designed just like the conveying device 10, i.e. with support rollers 15', 15", which are arranged distributed along the length of the distribution conveyor belt 28, and with guide elements 13', 13", 14', 14", which are
Here, too, the adjustment of the track rope length IT can take place at each of the anchor points Al, A2 or at both at the same time.

In Fig. 5, a particularly advantageous embodiment for filling in the region of the hollow base 2 .. is shown. In the region of the end of the conveying device 10 in the hollow 1, a distribution conveying device 25 is arranged suspended from the at least one track rope 4.
The convey-ing device 10 conveys the conveyed material 6 onto the distribution conveying device 25 and is conveyed from there into the hollow 1. In the illustrated embodiment, the distribution con-veying device 25 is designed as a distribution belt conveyor system, other configurations also being conceivable.
In the embodiment of the distribution conveying device 25 according to Fig. 5 as a distribu-tion belt conveyor system, the distribution conveying device 25 has two deflection rollers 26, 27 around which an endless distribution conveyor belt 28 revolves. At least one deflection roller 26, 27 is driven by a drive 29. In this example, the distribution conveying device 25 is designed with support rollers 30 on which the conveying run of the distribution conveyor belt 28 is supported. For the support rollers 30, load-bearing structures 31 are provided, which are arranged on the at least one track rope 4. Corresponding load-bearing structures 32, which are also arranged on the track rope 4, are also provided for the deflection rollers 26, 27. The distribution conveying device 25 could, however, be designed just like the conveying device 10, i.e. with support rollers 15', 15", which are arranged distributed along the length of the distribution conveyor belt 28, and with guide elements 13', 13", 14', 14", which are
- 8 -Date Recue/Date Received 2021-01-08 arranged suspended from the at least one track rope 4, preferably on corresponding sus-pended load-bearing structures.
Of course, a common load-bearing structure could also be provided for the distribution con-veying device 25, suspended from the track rope 4, on which the components required for the distribution conveying device 25 are arranged.
The distribution conveying device 25 in the form of a distribution belt conveyor system prefer-ably extends along the track rope 4 in both directions from the end of the conveying device in the hollow 1 and below the conveying device 10. The conveying device 10 conveys the conveyed material 6 onto the distribution conveying device 25 and is conveyed from there 10 into the hollow 1. By changing the direction of rotation of the drive 29, the distribution belt conveyor system can convey in both directions (as indicated in Fig. 5 by the double arrow).
In this way, two conical piles 24 can be heaped up onto the hollow base 2 with conveying material 6, which of course can facilitate and accelerate the filling process.
For example, one conical pile can be formed while the other is being spread.
One or more unloading points located between the two ends of the distribution conveying de-vice 25 could also be provided on the distribution conveying device 25, for example in order to form further conical piles 24, or to deposit the conveyed material 6 at other locations.
Likewise, the distribution conveying device 25 can only convey in one direction. In order to still be able in such an embodiment, or in other embodiments, to deposit the conveyed mate-rial at two points, for example two conical piles 24 as shown in Fig. 5, a switching chute can also be arranged between the conveying device 10 and the distribution conveying device 25, which either conveys the conveyed material 6 from the conveying device 10 onto the distribu-tion conveying device 25, or from the conveying device 10 next to the distribution conveying device 25 directly onto the hollow base 2. In the latter case, the distribution conveying device 25 can also stand still. The switching chute could be arranged suspended from the at least one track rope 4 or also on a load-bearing structure of the conveying device 10 or the distri-bution conveying device 25.
In the above preferred embodiments, suspended is understood to mean that the at least one track rope 4 is arranged at the very top and all other components, such as the load-bearing .. structure 11, 12, 31, 32, guide elements 13', 13", 14', 14", support rollers and the distribution belt conveyor system 25, are suspended therefrom. According to the invention, suspended is understood more broadly and also includes designs in which the track rope is arranged in the middle, i.e. certain components above and certain below the track rope 4, or at the very bot-tom, i.e. all components above the track rope 4.

Likewise, the distribution conveying device 25 can only convey in one direction. In order to still be able in such an embodiment, or in other embodiments, to deposit the conveyed mate-rial at two points, for example two conical piles 24 as shown in Fig. 5, a switching chute can also be arranged between the conveying device 10 and the distribution conveying device 25, which either conveys the conveyed material 6 from the conveying device 10 onto the distribu-tion conveying device 25, or from the conveying device 10 next to the distribution conveying device 25 directly onto the hollow base 2. In the latter case, the distribution conveying device 25 can also stand still. The switching chute could be arranged suspended from the at least one track rope 4 or also on a load-bearing structure of the conveying device 10 or the distri-bution conveying device 25.

An advantageous embodiment of an anchor point Al, A2 with a rope adjustment device 46 is explained with Fig. 6. In this embodiment, six track ropes 4 are provided, the following
- 9 -Date Recue/Date Received 2021-01-08 statements naturally being valid for any number of track ropes 4. At the ends of the track ropes 4, a first holding device 40 of the rope adjustment device 46 is fastened to the track ropes 4, for example via a clamp connection. These first holding devices 40 are supported on a first cross-member 41 through which the track ropes 4 are passed. The first holding de-vices 40 together with the first cross-member 41 must therefore support the entire weight of the track ropes 40, the conveying device 10 arranged thereon, and the weight of the con-veyed material 6 being conveyed. At a certain distance (in the direction of the other anchor point Al) from the first holding devices 40, second holding devices 43 are provided on the track ropes 4, which can be designed in the same way as the first holding devices 40. Fur-thermore, a second cross-member 42, through which the track ropes 4 are passed, is ar-ranged in a stationary manner, on which the second holding devices 43 can be supported.
The first cross-member 41 is arranged displaceably in the longitudinal direction of the track ropes 4 by means of an actuator. For this purpose, a linear actuator 44, for example a hy-draulic, pneumatic or electric actuator, which acts on the first cross-member 41, is arranged on a supporting element 45 of the anchor point A2. Such a linear actuator 44 is preferably provided on both sides of the track ropes 4. With the linear actuator 44, the cross-member 41 can be displaced in the longitudinal direction of the track ropes 4.
In order to pull the track rope 4 upwards, the procedure according to Fig. 6 can be carried out as follows. The holding devices 40 at the ends of the track ropes 4 are fastened to the track ropes 4 and are supported on the first cross-member 41. The linear actuator 44 is fully re-tracted. The linear actuator 44 is now actuated, with which the cross-member 41 is displaced in the direction away from the opposite anchor point Al - the track rope length IT is thus shortened by the stroke of the linear actuator 44. For safety reasons, the second holding de-vices 43 can also be fastened to the track ropes 4, which are thus also displaced with the track rope 4. When the linear actuator 44 is extended, these second holding devices 43 are released from the track ropes 4 and displaced to the second cross-member 42.
This can be done automatically or manually. If the second holding devices 43 are released from the track ropes 4 when the track ropes 4 are pulled, then under certain circumstances it is also possi-ble to dispense with displacing the holding devices 43 to the second cross-member 42. The second holding devices 43, that abut the second cross-member 42, are fastened to the track ropes 4 (manually or automatically), with which the track ropes 4 are now supported via the second holding devices 43 and the second cross-member 42. The linear actuator 44 can now be retracted again, with the result that the first cross-member 41 is displaced again in the direction of the opposite anchor point Al. The first holding devices 40 can then be re-leased from the track ropes 4 and displaced in the direction of the first cross-member 41 and fastened again to the track ropes 4 (manually or automatically). This can of course be re-peated until the desired shortening of the track rope length IT has been achieved.

In this case, another suitable holding device could be provided for holding the track rope 4 during the adjustment of the first holding devices 40.
Of course, other configurations of the anchor point Al, A2 and/or the rope adjustment device 46 for altering the track rope length IT are also conceivable. Another option for a rope adjust-ment device 46 would be, for example, a rope winch for a track rope 4 with a latch.
To extend the track rope length IT, the process would essentially proceed in reverse order. In this case, the linear actuator 44 could normally be extended and retracted to lengthen the track rope length IT. In order that the linear actuator 44 does not always have to be activated, a releasable latching of the first cross-member 41 could also be provided in the position of the extended linear actuator 44. Alternatively, the linear actuator 44 could also be arranged differently or a different actuator could be provided.
