Description
WO 2014/206587 PCT/EP2014/056294 1 ARRANGEMENT FOR CONTROLLING AUTOMATED OPERATION MODE Field of the invention The present invention relates to work machines, and more particularly 5 to controlling the automated operation mode of a work machine. Background of the invention Various mining vehicles, such as rock drilling equipment, loading equipment and transport equipment, are used in a mine. Mining vehicles may be manned or unmanned. Unmanned mining vehicles 10 may be remote-controlled by an operator from a control station, for instance, and they may be equipped with measuring instruments suitable for location determination. Unmanned mining vehicles may be operated automatically, e.g. driven along a desired route in the mine, as long as the location of the device can be determined. The 15 automated operation may be carried out in a surface or underground operating area. An automatically operated mining vehicle may encounter an unexpected condition, which may necessarily not be tackled by the 20 automated settings of the mining vehicle. Examples of such unexpected conditions may comprise locations in a hole being drilled comprising water or a fracture and locations where the properties of the rock material suddenly change. Such unexpected conditions may also relate to obstacles hindering the mining vehicle from moving to desired 25 direction. Typically, when an automatically operated mining vehicle encounters such unexpected condition, the automated operation is interrupted, the mining vehicle is stopped and possibly the operator at the remote control station is notified by an alarm. The operator may then take over the mining vehicle to remote manual operation and 30 solve the problem causing the interruption of the automated operation by operating the mining vehicle manually over the unexpected condition.
WO 2014/206587 PCT/EP2014/056294 2 However, taking over the mining vehicle to remote manual operation requires further operations of shutting down the automated operation mode and establishing a remote control channel to the mining vehicle 5 in order to operate the mining vehicle manually. On the other hand, taking over the mining vehicle to remote manual operation mode during the automated operation mode causes the mining vehicle to stop its operation immediately. Any such interruptions reduce the efficiency of the mining operations. Partly for this reason, operators at the remote 10 control station tend to allow the automated operation mode to continue until an unexpected condition is encountered, thereby possibly causing the mining vehicle to stop. However, the automated operation mode may have caused the mining vehicle to end up to a very difficult situation, and solving the problem caused thereby manually may take a 15 long time. Summary of the invention An improved method and technical equipment implementing the method has now been developed for controlling the automated 20 operation mode of the mining vehicle. Various aspects of the invention include a method, a working machine and a computer program product, which are characterized by what is stated in the independent claims.

These and other aspects of the invention and the embodiments related thereto will become apparent in view of the detailed disclosure of the embodiments further below. 30 List of drawings In the following, various embodiments of the invention will be described in more detail with reference to the appended drawings, in which WO 2014/206587 PCT/EP2014/056294 7 Fig. 1 shows a schematic representation of a rock drilling apparatus as an example of a work machine suitable for implementing the embodiments of the invention; 5 Fig. 2 shows a flow chart for a control method of a work machine according to an embodiment of the invention; Fig. 3 shows a block diagram of a system for carrying out the 10 control method of a work machine; and Fig. 4 shows an exemplified block diagram of co-functional modules according to an embodiment of the invention. 15 Description of embodiments The presently disclosed embodiments are applicable, in particular, to various remotely operatable work machines used in mining industry. Particular examples of such work machines are mining and construction apparatuses, such as various mobile rock drilling 20 machines. A mining apparatus may be a mobile mining apparatus, which may be referred to as a mining vehicle, or a stationary mining apparatus. It should also be noted that, in general, a mining apparatus may also refer to various machines used for rock excavation in a surface or underground operating area. In this context, the term "rock" 25 is to be understood broadly to cover also a boulder, rock material, crust and other relatively hard material. Fig. 1 shows an example of a rock drilling apparatus 100, such as a rock drilling rig comprising a movable carrier 102, one or more drilling 30 booms 104 and drilling units 106 arranged in the drilling booms 104. The drilling unit 106 comprises a feed beam 108 on which a rock drill 110 can be moved by means of a feed motor (not shown in Fig. 1). Further, the drilling unit 106 comprises a tool 112 with which the impact pulses given by a percussion device (not shown in Fig. 1) of the rock WO 2014/206587 PCT/EP2014/056294 8 drill 110 are transmitted to the rock to be drilled. The rock drilling apparatus typically comprises a plurality of pumps (not shown in Fig. 1) for generating hydraulic pressure for operating various parts of the apparatus, for pumping drilling fluid for lubricating, cooling, and 5 cleaning a drilling bit, and for pumping rock cuttings from the drill holes. The rock drilling rig 100 further comprises at least one control unit 114 arranged to control actuators of the rock drilling rig 100, the actuators being arranged in a first control system. The control unit 114 may be a 10 computer or a corresponding device, and it may comprise a user interface with a display device as well as control means for giving commands and information to the control unit 114. The control unit 114 and its user interface are typically located within a cabin 116 of the rock drilling apparatus 100. 15 Further, the rock drilling apparatus 100 may have a data transfer unit 118, with which the control unit 112 may establish a data transmission connection to a second control system external to the rock drilling apparatus 100 by utilising a wireless connection provided by a base 20 station 120. The second control system may reside at a control station 122 that may be arranged outside the mine. The control systems may be computers equipped with appropriate software. A remote operator 124 may monitor and control the operations of the rock drilling apparatus 100 via the wireless connection. 25 Figure 1 is a simplified figure, and the control system of a mining vehicle, such as the rock drilling apparatus 100, typically comprises several units for implementing different control functions. The control system of the mining vehicle may be a distributed entity consisting of 30 modules connected to a CAN (Controller Area Network) bus, for example, and managing all measurements and controls of the machine. The information system of the control station 122 may also comprise one or more servers, databases, operator workstations and a connection to other networks and systems. 35 WO 2014/206587 PCT/EP2014/056294 9 The rock drilling rig of Figure 1 is disclosed herein only as an example of a mining vehicle where the embodiments disclosed herein may be implemented. The embodiments are equally applicable to any other mining vehicles, such as various loading and transport equipment used 5 in mines. Despite of whatever mining vehicle is used, the control system of the mining vehicle preferably comprises a positioning system or unit. Various methods may be used for determining the location of the 10 mining vehicle, for example, depending on whether the mining vehicle is used in surface drilling or in underground drilling. In surface drilling, it is possible to use satellite navigation, such as the GPS system, for determining the location and orientation of the mining vehicle with sufficient accuracy. 15 In underground drilling, the location of the mining vehicle may be determined using a tachymetry process. A sufficient number of navigation points with predetermined locations, for example in a tunnel to be excavated, are used for linking a tachymeter to the xyz 20 coordinate system to be used. The mining vehicle is provided with targets, the locations of which in relation to the origin of the coordinate system of the mining vehicle have been determined. The tachymeter is used for continuously measuring the xyz coordinates of the targets. Moreover, at least one point of the drilling pattern is determined in a 25 level of navigation. On the basis of these data, possibly together with a curvature table, the length of the drilling pattern and the inclination of the mining vehicle, the mining vehicle may determine its location and the location and the orientation of the drilling pattern. 30 Furthermore, regardless of whether a satellite navigation or a tachymetry process is used for determining the location of the mining vehicle, the mining vehicle and its sub-units, such as the drilling apparatus having its booms and drilling unit, are preferably provided with sufficient number of sensors, such as gyroscopes, compass 35 sensors, inclinometers, rotary encoders, linear encoders and WO 2014/206587 PCT/EP2014/056294 10 accelerometers, for ensuring sufficient hole position accuracy both for the feed alignment and the drilling process. As a result, when the mining vehicle navigated with sufficient accuracy carries out a drilling process according to a drilling pattern, exact locations are obtained for 5 the drilled holes and they can be exactly located in the coordinate system of the job site to be used as future reference holes. Thus, the operations of the mining vehicle may be remotely controlled and monitored, as well as be automated to be carried out at least partly 10 autonomously. The mining vehicle may further be arranged to obtain information about the operations of the mining vehicle, as well as about the area where the mining vehicle is operating. In the field of mining vehicles, an 15 automated drilling process generally refers to any operations, by which the mining vehicle is moved in its operating area, positioned as exactly as possible to a hole to be drilled and carries out the drilling process. For example, the rock drilling apparatus 100 may be provided with 20 various sensors to detect states of actuators and/or to measure conditions of different parts of the apparatus and possibly to take measurements about the environment. The sensors may include various types of pressure sensors, accelerometers, magnetometers, temperature sensors, etc. capable of providing real-time 25 measurements about the drilling process in general, particularly about the conditions at the drill bit on one hand, and about the properties of geological formation on the other hand. These real-time measurements are referred to as measurement-while-drilling (MWD) or logging-while drilling (LWD). 30 On the basis of the measurements from the sensors, MWD may provide drilling mechanics information. The information provided by MWD about the conditions at the drill bit may include, for example, rotational speed of the drill, smoothness of the rotation, rotating 35 pressure, pressure on the percussion piston, torque and weight on the WO 2014/206587 PCT/EP2014/056294 11 drill bit, vibration type of the drill bit, temperature in the hole, energy of percussion and rotation per drilled volume/length, penetration per impact, penetration per bit revolution, rotation torque, feed force, rotation-feed pressure ratio, feed pressure-penetration rate ratio, etc. 5 Furthermore, measurements may be made for obtaining a detailed record (log) of the geologic formations penetrated by a drill hole. In such measurements, information about geological characteristics around the drill hole, such as density, porosity, cleavage, resistivity, 10 fractioning, magnetic resonance and formation pressure, are obtained. Instead of or in addition to measurement information obtained from the rock drilling apparatus, there may be a separate measurement system arranged to obtain one or more types of information regarding the 15 drilling mechanics and/or the geologic formations. Such separate measurement system may be functionally connected to the rock drilling apparatus, for example, for transferring the measurement information to the rock drilling apparatus. 20 Depending on the field of drilling and the forum of discussion, the definitions of MWD and LWD may vary, and therefore at least some of the measurements mentioned above may sometimes be referred to as logging-while-drilling (LWD). 25 Typically, when starting to excavate rock, a drilling pattern is designed comprising at least the locations and the hole direction angles of the holes to be drilled in the coordinate system of the drilling pattern, as well as the lengths of the holes to be drilled. While drilling the drill holes according to the drilling pattern, the rock drilling apparatus is preferably 30 arranged to obtain measurement data from the drilled holes. The measurement data may comprise, for example, one or more data types of the MWD and/or the LWD data mentioned above. The measurement data may also comprise various analysis data regarding, for example, the drilling dynamics and/or the geologic formations, wherein for 35 example one or more data types of the MWD and/or the LWD data are WO 2014/206587 PCT/EP2014/056294 12 used as input data for various analysis algorithms. The measurement data may be stored on a memory medium in functional connection with the control unit. 5 Now according to an aspect of the invention, the work machine is arranged to control the automated drilling process on the basis of the data regarding previous operations of the work machine. Fig. 2 illustrates a method for controlling an automated drilling process on a work machine, such as the rock drilling apparatus. 10 In the method, data determining operations of the work machine are obtained (200) from at least one input. Reference data is generated (202) based on the data determining previous operations of the work machine in substantially the same area. A region of interest is detected 15 (204) in the reference data, and in response to the work machine or its drilling process approaching a point corresponding to the region of interest in the reference data, the work machine is controlled (206) to provide an operator with an option to manually assist the operations of the work machine at said point. 20 In other words, the operations of the work machine are monitored and reference data is generated on the basis of data determining previous operations of the work machine in substantially the same area. Herein, the data determining previous operations may be measurement data 25 obtained from one or more sensors of the work machine. It is also possible to use measurement data obtained from at least one other work machine. For example, another mining vehicle may have been operating in the same operating area previously and may have gathered measurement data using its own sensors. This measurement 30 data may be conveyed to the work machine in question e.g. via remote control station or by direct wireless transmission between the work machines. The data determining previous operations may also be user data 35 submitted by an operator of at least one work machine describing WO 2014/206587 PCT/EP2014/056294 13 operation conditions of an operating area and/or the work machine. Thereby, the data may be so-called silent knowledge gathered from experience of another operator. Thus, a previous operator may have stored information relating to e.g. problematic drilling conditions at a 5 certain location and/or depth or obstacles on a navigation route. The stored data may also relate to the work machine in question e.g. difficulties in carrying out certain operations by the work machine. The reference data may be MWD and/or LWD data from the previously 10 drilled one or more holes, for example. The reference data may be data received from one or more scanners or distance measuring devices about the environment of the work machine. Thus, the reference data may be data describing geological surface formations of the mine, for example in terms of its suitability for the propagation of the work 15 machine. The reference data may be analysed, if necessary, and a region of interest may be found in the reference data. Herein, the region of interest refers to any data or analysed information, which may have 20 influence on the overall operation of the work machine in its current location. Especially, it may refer any data relating to a location in one or more previously drilled holes or a location derived on the basis of one or more previously drilled holes, which may have influence on the drilling process of the work machine. The region of interest may further 25 be, for example, a region in the reference pattern, one or more holes, one or more hole depths, one or more hole depth intervals, data about detected obstacles, such as tunnel wall or loose rock, that may be relevant to the propagation of the work machine, etc. 30 At a moment, the operations of the work machine approach a point corresponding to the region of interest in the reference data, which may refer to the drilling process of at least one hole being drilled approaching a point corresponding to the region of interest in the reference data, the region of interest being, for example, a location 35 comprising water or a fracture or a location where the properties of the WO 2014/206587 PCT/EP2014/056294 14 rock material change. It may also refer to the work machine moving towards a location where a previously detected obstacle may hinder the propagation of the work machine. 5 When the operations of the work machine approach such a point, the work machine is controlled to provide an operator with an option to manually assist the operations of the work machine at said point. The operator may be a remote operator at a remote control statin or an operator in the cabin of the work machine. In case of the remote 10 operator, the control unit of the work machine may send a notification to the control system of the remote control station possibly arranged outside the mine. The notification may be provided on the user interface of the remote control station such that the remote operator preferably notices the notification. After considering whether the 15 situation is such that a manually assisted operation could improve the performance of the work machine over the detected region of interest, the remote operator may initiate an appropriate manually assisted operation. 20 The above arrangement is similarly applicable, when the work machine is carrying out an automated drilling process such that the operator is located in the cabin of the work machine. Similarly, said notification may be provided on the user interface of the work machine such that the operator preferably notices the notification. The operator in the 25 cabin then carries out the manually assisted operation, if considered necessary. According to an embodiment, in response to the manually assisted operation carried out by the remote operator is completed, the work 30 machine is controlled to continue the automated drilling process. Thus, when the remote operator has manually assisted the work machine over the detected region of interest, the work machine returns to continue the automated drilling process. Thus, no interruptions of the operation of the work machine are caused and the efficiency of the 35 drilling process may be maintained high.
WO 2014/206587 PCT/EP2014/056294 15 According to an embodiment, the manually assisted operation relates only to a sub-process of the automated drilling process, and other sub processes of the automated drilling process of the work machine are 5 continued while the operator carries out said manually assisted operation. Thus, operator may concentrate to a specific problem requiring human intervention, while the work machine otherwise may continue its automated operation. 10 According to an embodiment, the manually assisted operation comprises, in response to providing said option, establishing a control channel between a control station and the work machine; receiving manually submitted control commands via said control channel at the work machine; and disconnecting said control channel such that the 15 automated drilling process is continued. Thereby, the remote operator may be provided with the option to take control of the work machine, for example by displaying a notification on the UI of the remote station: "A cleavage approaching at the depth of 20 3.5 m, estimated time 40 seconds." In response to noticing the notification, the remote operator may start to manually controlling the drilling process, whereby the control responsibility is automatically shifted to the remote operator. The control responsibility remains at the remote operator as long as he/she continues to manually control the 25 drilling process, and upon stopping the manual control, the work machine automatically returns to the automated operation mode. As another option, The UI of the remote station may be provided with control means, such as a button, for the remote operator to take the manual control. 30 In order to the remote operator manually controlling the work machine, a wireless control channel is established between the control station and the work machine. The UI of the remote station may be provided with a plurality of views, such as one or more camera views captured 35 from the viewpoint of the work machine and one or more map views WO 2014/206587 PCT/EP2014/056294 16 showing the location of the work machine in respect to the geography of the mine and/or the drilling pattern and/or other work machines operating in the same area. On the basis of these views and using the control means of the remote station, such as a joystick and/or a mouse 5 and/or a touch pad and/or a touch display, the remote operator starts to operate the work machine manually over the difficult position. The control signals of the control means are transmitted as control commands via said control channel to the work machine. The remote 10 operator may continue to operate the work machine manually as long as necessary such that the difficult position has been passed. Then the remote operator may terminate the manual operation by disconnecting the control channel, whereupon the work machine automatically returns to continue the automated drilling process. 15 Instead of providing the remote operator with an option to manually control the operation of the work machine using the control means of remote station over the control channel, the remote controller may be provided with an option to select a predetermined operation to be 20 carried out. Thus, according to an embodiment, the manually assisted operation comprises determining one or more functionalities for assisting the operations of the work machine at said point; providing the remote 25 operator with said one or more functionalities as options to select; in response to the remote operator selecting one of said functionalities, carrying out control operations according to the selected functionality at the work machine; and continuing the automated drilling process. 30 Herein, the work machine may be arranged, upon noticing that the operation is approaching a point corresponding to the region of interest in the reference data, to determine one or more functionalities that may assist the operations of the work machine in a difficult position. The remote operator may then be provided with said one or more 35 functionalities as options to select, for example by displaying a WO 2014/206587 PCT/EP2014/056294 17 notification on the UI of the remote station: "A point possibly comprising water approaching in 50 cm. Want to switch off suction?" The UI of the remote station may be provided with selection means, such as a button, for the remote operator to select at least one functionality to be 5 carried out. Herein, no wireless control channel needs to be established between the control station and the work machine, but the selection of the remote operator may be transmitted to the work machine along with 10 other communication between the control station and the work machine. The work machine carries out the predetermined functionality selected by the remote operator as a part of the automated process and continues then the automated drilling process. 15 According to an embodiment, the control operations according to the selected functionality comprise at least one of the following: - automatically switching off suction of drilling cuttings in response to the reference data indicating the drilling process of the hole being drilled approaching a point comprising water; 20 - reducing drilling feed power in response to the reference data indicating the drilling process of the hole being drilled approaching a void; - adjusting drilling feed power and/or percussion to be suitable for expected type of rock material; 25 - changing the drilling control mode and/or the drilling control parameters according to the expected rock conditions. Consequently, when a region of interest possibly having a major or a severe influence on the drilling process of the hole being drilled is 30 detected in the reference data, the remoter operator may be provided with an option to control the drilling process appropriately by adjusting at least one parameter of the drilling process.
WO 2014/206587 PCT/EP2014/056294 18 According to an embodiment, the control operations according to the selected functionality comprise changing navigation route of the work machine in response to at least one of the following: - detecting a forbidden area on a planned route; 5 - detecting the work machine to be too inclined; - detecting a difficult position on a planned route. Thus, in a manner similar to detecting possible difficulties in the drilling process, when the reference data comprises a region of interest, which 10 may involve an obstacle for the movements of the work machine, the remoter operator may be provided with an option to change the navigation route accordingly. Such an option may also be provided if, for example, the work machine, such as a drilling rig, is in a too inclined alignment such that the work machine cannot be driven along the 15 originally planned navigation route. A further example relates to detecting a difficult position, such as a tunnel wall or an edge of a bank, being close to the planned route, whereupon the remoter operator may be provided with an option to change the navigation route to avoid said position. 20 The manually assisted operations may further relate to supporting the work machine to be firmly in its operating position. For example, a drilling rig should be firmly supported in its operating position, possibly obtaining ground contact through one or more ground supports, before 25 it can be safely and steadily operated. Thus, according to an embodiment, the control operations according to the selected functionality comprise manually assisting in providing ground support of the work machine in response to at least one of the 30 following: - detecting the ground around the work machine to be too inclined or slippery to support; - detecting the work machine to be too inclined to support; - detecting at least one support of the work machine being incorrectly 35 supported.
WO 2014/206587 PCT/EP2014/056294 19 Herein, the work machine may observe the reference data relating to the ground around the work machine, and if a region of interest indicating the ground to be, for example, too inclined or slippery to 5 support the work machine is detected, the remoter operator may be provided with an option to manually assist in providing ground support of the work machine. In a similar manner, it may be detected that the work machine, such as a drilling rig, is too inclined to be supported or supporting the work machine has failed, the remoter operator may 10 again be provided with an option to manually assist in providing ground support of the work machine. A further field of operation where the manually assisted operations may be provided to the operator is positioning the work machine, for 15 example as described above in connection with the drilling apparatus having its booms and drilling unit each being positioned in their correct operating position. Therefore, according to an embodiment, the control operations 20 according to the selected functionality comprise manually assisting positioning the work machine and/or its sub-units in response to at least one of the following: - obtaining a pre-warning of collision; - detecting a feed beam touching ground; 25 - detecting a feed beam leaning on a tunnel wall; - detecting at least one of the joints of the work machine not following correctly. Herein, the pre-warning of collision may relate to a situation, where the 30 work machine starts to operate in a difficult position such that there is a risk of a boom to collide into another part of the work machine, e.g. a cabin or the boom itself. The operator may manually assist e.g. by controlling one of the joints of the work machine to move to a position where the automated process may continue. This may also be the 35 manually assisted operation, when it is detected at least one of the WO 2014/206587 PCT/EP2014/056294 20 joints of the work machine does not follow correctly. If it is detected that the feed beam touching ground or leaning against a tunnel wall, this may be indicated to the operator, who then controls the feed beam to move to such position where the automated process may continue. 5 According to an embodiment, one or more sets of drilling parameters, drilling control modes and/or drilling control parameters are stored in a memory of the work machine. In the memory, each set of drilling parameters, a drilling control mode and/or a drilling control parameter 10 may be linked to one or more drilling conditions, where such parameters or control modes are suitable to use. The drilling parameters, drilling control modes and/or drilling control parameters may be determined on the basis of at least one previously drilled hole, or they may be calculated using an appropriate algorithm. 15 According to an embodiment, in response to the reference data indicating the drilling process of the hole being drilled approaching a specific rock condition, the work machine is arranged to retrieve from the memory a set of drilling parameters, a drilling control mode and/or 20 a drilling control parameter suitable for said drilling condition to be used in said control operations. In a use case example, the work machine is in an automated process drilling rock type A with good drilling parameters (e.g. good penetration 25 rate, low levels of vibrations). The used drilling parameters have been stored in the memory and linked to the rock type A. Next, the work machine moves to drill rock type B and makes changes to the drilling parameters. Later on, the drilling process moves back to rock type A. Now, upon the reference data indicating the drilling process of the hole 30 being drilled approaches rock type A, the previously stored drilling parameters offering high penetration rate with low levels of vibrations for the rock type A can be retrieved from the memory. Herein, the work machine may be arranged to send a notification to the 35 remote station, the notification showing the stored drilling parameters WO 2014/206587 PCT/EP2014/056294 21 for the rock type A and proving an option to take said drilling parameters in use. The remote operator may then select to use said parameters and give a user input via the UI of the remote station to the work machine for using said drilling parameters. 5 In a similar manner, when the work machine is operating in a mine, it may be arranged to store its navigation parameters together with corresponding propagation conditions, and when later on operating substantially in the same area, the sored parameters may be utilised. 10 Thus, according to an embodiment, one or more sets of navigation parameters are stored in a memory of the work machine, said set of navigation parameters are linked to one or more propagation conditions, where such parameters are suitable to use, and in response to the reference data indicating the navigation route of the 15 work machine approaching an obstacle, a set of navigation parameters suitable for propagation to be used in said control operations is retrieved from the memory. According to an embodiment, the remote operator may be provided 20 with an option to include his/her notes to the user interface view of the remote station. The note may relate to a certain event in the drilling process (e.g. detected water or fractioning) or to navigation (e.g. an area where manually assisted navigation is typically required) or to an operation or an observation made by the operator, and the operator 25 may include a note, such as a text or a voice message, describing the event more in detail. The user interface of the apparatus may include a specific button ("event button") or any other input means for including the note relating an event. 30 In the previous embodiments, the reference data may, at its simplest, be based on data from only one previously drilled reference hole. The reference hole may be, for example, the latest drilled hole or a hole locating closest to the hole being drilled. The reference hole may also be any other previously drilled hole, selected for example from a field 35 view of a drilling plan.
WO 2014/206587 PCT/EP2014/056294 22 According to an embodiment, the reference data may be based on measurement data from a plurality of previously drilled holes comprising for example a row of reference holes, a fan of reference 5 holes, any other part of the drilling pattern or the whole drilling pattern. Thus, the reference data may be based on measurement data from two or three previously drilled holes, for example. The reference data may further be based on measurement data from 10 one or more holes previously drilled using the same or another drilling rig, from one or more previously drilled exploration holes (e.g. boreholes), from analysis data of chippings, or from geological data obtained otherwise than by drilling, e.g. by scanning or imaging a bank or the ground, or by using a geological map or a mine map/scheme. If 15 the measurement data is obtained otherwise than by drilling, then a previously drilled hole may be a virtual hole, which calculated and/or estimated on the basis of said measurement data.
