Abstract
The present invention relates to a cancem filling type coal-mining method. Said method includes the following steps: building main shaft, auxiliary shaft, road large tunnel, haulage drift, ventilation drift and setting stope face, and when the coal is extracted, it adopts cavem filling mode, including the following steps: dividing stope face, presetting horizontal drief on the stope face, one-by-one extracting coal form horizontal drift, after every drift is extracted, filling the empty drift with coal gangue, and its filling rate is greater than or equal to 80%.
Description
Technical field
The present invention relates to the coal mining method, especially the exploitation method in the slow down tiltedly layer of building coal seam belongs to the coal-mining technique field.
Background technology
Tradition mine to adopt and to hollow out the formula coal-mining method, begins digging by the farthest in the exploiting field of delimiting, and digging is installed support apparatus and subsided preventing to a certain degree the time, continues digging thereafter, and support apparatus will be torn open thereupon and move, and original mining site is let alone to cave in.Hollow out the formula coal-mining method and running into more shallow coal seam, and when on the ground, place, coal seam building or village being arranged, the digging meeting has a negative impact to the face of land at building or place, village, though relevant rules are to mining in such cases, all restrictive regulations have been made, and some standards have been formulated, the safety in entail dangers to building or village not, but in practice, mining operations still can be built coming down hard upon of the owner and villager, cause the coal seam under the village to exploit, make the idle waste of a large amount of coal resources, the exploitation of coal is a great problem that coal industry faces under building and the village.
In addition, coal industry also has a difficult problem, the i.e. handling problem of gangue.In traditional coal mining activity, the gangue that digging is come out is stacked to ground by the mine delivered downhole, formation coal gangue hill of a specified duration.Spontaneous combustion can take place depositing in the process of long period in a large amount of gangues, discharges multiple oxious component, and environment is polluted.How handling existing gangue, and prevent new gangue accumulation, is another difficult problem that coal industry faces.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes above-mentioned coal-mining method, the coal-mining method that a kind of cavern filling type is provided.
The alleged problem of the present invention realizes with following technical scheme:
A kind of cavern filling type coal mining method, it comprises sets up main shaft, auxiliary shaft or ventilating shaft, and digging leads to the big lane of track, main haulage roadway and the airway in exploiting field, set up stope, its unique distinction is that coal mining activity adopts cavern filling type, and concrete steps are:
A. in the exploiting field, along inclined direction divide stope, and the exploitation tunnel of in each stope, moving towards by spaced mode delimitation level in advance;
B. the coal in the topmost tunnel delimited in advance of exploitation, exploitation finish the back with filling tunnels such as gangues,
C. exploit downwards the coal in each tunnel successively, and with fillings such as gangues;
D. after the exploitation of first stope finishes, exploit second stope again, repeat above-mentioned steps.
Above-mentioned cavern filling type coal mining method leaves the coal column of 10-20 rice between the described stope.
Above-mentioned cavern filling type coal mining method, the spacing between the exploitation tunnel of described spaced level trend is more than or equal to the lateral dimension in cross section, tunnel.
Above-mentioned cavern filling type coal mining method, the shape in cross section, described tunnel can be arch, trapezoidal, and the gabarite in tunnel can be selected in 2～5 meters scopes.
Above-mentioned cavern filling type coal mining method, the filling rate of described gangue are 〉=80%.
When adopting the inventive method to mine, the down-hole digging gangue is filled in the tunnel, forms the band exploitation, replace coal with spoil, the tunnel after the exploitation can not cave at short notice, surface deformable can not occur.Can eliminate the building owner and villager's trouble and worry, make the coal resources under building and the village be able to exploitation as much as possible, solve the problem of seam mining difficulty under the village.The gangue that produces in the exploitation can be used as filler and is backfilling in the tunnel, needn't be promoted to ground, has saved the lifting expense, and has stopped the source of gangue formation hillock.In addition, the present invention also has enforcement easy and simple to handle, easy, investment characteristics such as little, adopts in the exploitation of under building and the village gently inclined seam of suiting especially.
Description of drawings
Fig. 1 implements cavern filling type exploitation method schematic diagram;
Fig. 2 is an A-A sectional drawing among Fig. 1.
The specific embodiment
Consult Fig. 1,2, suppose that the diagram coal seam is a gently inclined seam, coal seam thickness is about 4 meters, the key step of exploitation is: set up main shaft 1, auxiliary shaft or ventilating shaft 2, shaft station 3, digging leads to the track 4 of going up a hill, the conveying track 5 of stope, marks the tunnel 7 of row of horizontal trend in stope 6 in advance, and many entrys arranged side by side from top to bottom are intervally arranged along the seam inclination direction.Drift section is shaped as arch, and the import in each tunnel is gone up a hill with ginney and transportation and is connected, and span length is established 4 meters, highly is 3.5 meters that the distance between the upper and lower tunnel also is 4 meters.The tunnel is filled with gangue etc. in coal in the entry at the elder generation top of digging, the exploitation back that finishes, the coal in each predetermined tunnel of digging in order from top to bottom then, one of digging, one of filling, spoil filling rate 〉=80%.Can adopt the mechanical work mode during filling, concrete operations are, place an adhesive tape in the empty tunnel after digging and carry the cash machine of throwing, the shop is applied fortune coal track in the tunnel and coal conveyor gangue etc. is transported in the tunnel when utilizing digging, gangue in the coal conveyor is poured over adhesive tape to be carried on the conveyer belt of throwing the cash machine, when conveyer belt rotates at a high speed with the gangue throwing to the termination, tunnel, the tunnel is filled up.During filling, fill while retreating to the port of export, throw the cash machine and move subsequently with throwing by inner end, tunnel.The gangue that gangue accumulates from the gangue that produces in the digging or mine.Answer Bian Caibian on the surface, tunnel, to add the metal bolting with wire mesh during mining operations, come off to prevent that the tunnel from caving in.
Still consult Fig. 1,, when seam inclination length is big, for the benefit of ventilate, can mark off a plurality of stopes, in each stope, mark a plurality of tunnels arranged side by side by the predeterminated level trend when building or village floor space are bigger.In line with from top to bottom, from the superficial to the deep principle exploits the coal in each stope and each entry one by one.In the illustrated embodiment, divided distance between 6, two stopes of 3 stopes in 10～20 meters scopes, the step of exploitation is the same.
This coal-mining method is applicable to nearly level or the slow tiltedly coal mining in layer coal seam under village or the building.
