Abstract
The present invention provides a thick-coal-seam large-mining-height gob-side roadway retaining method which comprises the following operating steps: 1) arranging supporting pillars on the side, near a stoping area, of a roadway; 2) arranging a filling layer and a rubber air bag layer between the supporting pillars and the stoping area; 3) arranging a latticed strengthening protecting net at the top of the roadway, wherein the latticed strengthening protecting net is embedded into the top rock stratum of the roadway through anchor ropes; 4) further arranging a layer of light-reflecting air cushion layer at the bottom of the latticed strengthening protecting net; 5) inflating the rubber air bag layer, filling the filling layer with concrete, and when the concrete is concreted, removing the rubber air bag layer; 6) along with the propulsion of the stoping working surface, repeating the steps till the whole roadway is finished. Through the designed filling layer and rubber air bag layer in the steps, the rapid propulsion of the filling layer in thick-coal-seam large-mining-height gob-side roadway retaining can be effectively realized; the latticed strengthening protecting net at the top of the roadway is embedded into the filling layer to form an integrity, so that the structural stability of the whole roadway is improved.
Description
Technical field
The present invention relates to gob side entry retaining field, coal seam, be specifically related to a kind of thick seam large mining height along empty
Stay lane method.
Background technology
Along with present socioeconomic development, the living standard of people is also constantly promoting,
Coal resources, one of energy mineral resources.25% is accounted in world's primary energy consumption figure.I
The reserves of state's coal resources relatively horn of plenty, but owing to the economy of China is when development, for money
Asking for of source resource is the strongest, and the yield consuming coal in production accounts for world's coal production
45%, yield ranks first in the world.
But limited due to coal resource, and in the middle of the exploitation of China's last 100 years, by major part
Earth's surface seam mining totally, research is that the important of present mine coal is ground in the coal seam of underground deep layer
Studying carefully direction, although rich reserves in subterranean coal, coal seam is thicker, but during exploitation the most easily
Cause danger, wrongful exploitation, can bring huge economic loss and casualties.And it is thick
During seam mining, easily produce wasting of resources phenomenon.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of thick seam large mining height gob side entry retaining
Method, it is possible to effectively realizing the exploitation of effective year of the effective high seam for high seam, increase is opened
The effective area adopted and the structural stability in tunnel promote.
For realizing object above, the present invention is achieved by the following technical programs:
A kind of thick seam large mining height gob-side entry retaining method, operating procedure is as follows:
1) in tunnel, back production district one side is provided with pillar；
2) packed layer and rubber pneumatic bag floor are set between pillar and back production district；
3) top in tunnel arranges the anti-net of latticed reinforcement, and anchor cable is crossed by the anti-Netcom of latticed reinforcement
Embed in the cap rock layer in tunnel；
4) bottom at the anti-net of latticed reinforcement arranges one layer of reflective air cushion layer again.
5) rubber pneumatic bag layer is inflated, then fill concrete in packed layer, treat concrete
Solidification, removes rubber pneumatic bag layer；
6) along with the propelling repeat the above steps of stope, until the completing of whole tunnel.
Preferably, described step 2) in often to arrange the spacing between pillar be 20-50cm.
Preferably, the two ends of described anchor cable are claw-like structures, and are connected by middle pole.
Preferably, a length of 30-40cm of described pole.
Preferably, the anti-net of described latticed reinforcement embeds in packed layer, the coagulation in layer to be filled
Soil solidification, forms entirety.
Preferably, described pillar is that fluid pressure type inflates post.
The invention provides a kind of thick seam large mining height gob-side entry retaining method, by step designs
Packed layer and rubber pneumatic bag layer, when effectively achieving thick seam large mining, quickly pushing away of packed layer
Enter, and the top net trellis in tunnel is strengthened anti-net and embedded in packed layer, forms entirety, promotes
Overall tunnel structural stability, it is simple to the back production district of high seam carries out seam mining.Whole
Method can be promoted in deep seam mining.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below
The accompanying drawing used required in embodiment or description of the prior art will be briefly described, aobvious and
Easily insight, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
The overall structure schematic diagram of Fig. 1 present invention；
Wherein: 1, tunnel；2, back production district；3, pillar；4, packed layer；5, rubber pneumatic bag
Layer；6, the anti-net of latticed reinforcement；7, reflective air cushion layer；8, anchor cable；81, pole.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below will knot
Close the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear,
It is fully described by.Based on the embodiment in the present invention, those of ordinary skill in the art are not making
Go out the every other embodiment obtained under creative work premise, broadly fall into present invention protection
Scope.
As it is shown in figure 1, the present embodiment provides a kind of thick seam large mining height gob-side entry retaining method, operation
Step is as follows:
1) in tunnel 1, back production district one side is provided with pillar 3；
2) packed layer 4 and rubber pneumatic bag floor 5 are set between pillar 3 and back production district 2；
3) top in tunnel 1 arranges the anti-net of latticed reinforcement 6, and the anti-net of latticed reinforcement 6 leads to
Cross in the cap rock layer that anchor cable 8 embeds tunnel 1；
4) bottom at the anti-net of latticed reinforcement 6 arranges one layer of reflective air cushion layer 7 again.
5) rubber pneumatic bag layer 5 is inflated, then fill concrete in packed layer 4, wait to mix
Solidifying soil solidification, removes rubber pneumatic bag layer 5, easy and simple to handle；
6) along with the propelling repeat the above steps of stope, until the completing of whole tunnel 1.
Step 2) in often to arrange the spacing between pillar 3 be 20-50cm.
