Abstract

The present invention is a kind of coal-mining method of clean and effective, is suitable for mine field of solid waste treatment.According to the solid waste discharge amount that mine generates, including underground gangue and ground flyash, the width of short section working face is designed；The first two adjacent short section working faces of filling mining carry out suspension roof support along filling face edge and entity coal side and retain tunnel；The system that the tunnel that two short section working faces retain constitutes long section working face with intermediate coal body；Long section working face is exploited, while jumping both sides short section filling operation face of adopting, the spoil that long section working face generates also is transported to short section working face simultaneously and is filled, to realize the continuous mining system of short face filling mining, long face high winning technology.The present invention can handle all solid waste of grass and underground, reduce the cost of gangue treatment, alleviate the damage to ecological environment, while forming tunnel using solid waste bashing, eliminate coal column, improve the rate of recovery of resource.

Description

A kind of coal-mining method of clean and effective
Technical field
The present invention relates to a kind of coal-mining methods of clean and effective, are particularly suitable for mine field of solid waste treatment.
Background technology
With the continuous integration of national resources, produces ten million ton of large-scale mine per year and be on the increase so that mine generated consolidates The growth of explosion type is presented in body waste, and coal mine solid waste is most importantly gangue, washing spoil, flyash, now The mode of processing is to concentrate air storage mostly, is not only damaged to mining area ecological environment, but also to mining area personnel existence ring It causes to seriously threaten in border.
According to the overall planning of country and requirement, the construction of new-modernization coal mine is China's Dissertation of Development of Coal Industry from now on Direction promotes the target of safety of coal mines low-carbon operation and sustainable development, and therefore, mine solid waste processing mode has to Change, the new model of mining area solid wastes recycling comprehensive utilization need to be explored.In recent years, coal mining enterprise is it is also proposed that the way comprehensively utilized Diameter, for example, solid waste power generation, production construction material, recycling beneficial to mineral products, produce chemical products, improvement soil, production fertilizer, Backfill (including building backfills, fills out low-lying land and wasteland, fills mine goaf, Subsidence Land in Coal Mining Area is reclaimed) is built the road, but not It can thoroughly solve the problems, such as fixed-end forces, still lack a kind of not only quick processing ground solid waste at present but also realize downhole solid The coal-mining method of waste not gug.
Invention content
Technical problem：The purpose of the present invention is overcoming the shortcomings of in prior art, it is solid to provide a kind of both quick processing ground Body waste realizes the coal-mining method of the downhole solid waste not clean and effective of gug again.
Technical solution：To realize the above-mentioned technical purpose, the coal-mining method of clean and effective of the invention, it is characterized in that including such as Lower step：
A. the volume for the solid waste that existing mine generates is calculated, solid waste includes underground gangue and ground Gangue, flyash；
B. the length section working face for filling mine solid waste is arranged in mine field with "nine squares" coal seam, in long section working face Both sides are respectively arranged short section working face I and short section working face II, arrange that the width of shortwall is w, I He of debugging short section working face Coalcutter, hydraulic support in short section working face II and belt-conveying machine equipment, while exploiting short section working face I and short section work Face II fills the gangue generated in the solid waste of existing mine and exploitation in exploitation, to filling face side What edge and entity coal side carried out that suspension roof support retains filling face both sides stays lane；
C. after short section working face I and short section working face II are exploited, using development machine in short section working face I and short section work Make to tunnel out open-off cut between face II, to make what short section working face I, short section working face II retained lane and open-off cut is stayed to constitute Long section working face mining system；
D. exploit long section working face I, at the same shift the winning apparatus of short section working face I to left side short section working face III into The short section working face IV of row exploitation, winning apparatus to the right side of transfer short section working face II is exploited, long section working face mining The gangue of middle generation is also transported in short section working face III and short section working face IV and is filled, after long section working face I is exploited Goaf is formed, goaf is directly caving.
E. after short section working face III and short section working face IV have been exploited, then open-off cut is tunneled respectively, be respectively arranged long section Working face II and long section working face III repeat step d, to realize that short section working face filling mining, long section working face efficiently return The continuous exploitation adopted, and so on, complete the exploitation in entire field with "nine squares" coal seam.
All short section face widths are identical, and using formula w=Q/ (2l*h), w≤60m determines that specific size is by solid Discarded object amount Q is determined, in formula, l is short section face length, and h is short section working face mining height.
All long section face widths are 150m~300m.
The span length retained after the short section working face filling is 4~6m.
Advantageous effect：By adopting the above-described technical solution, the present invention has the following advantages that compared with prior art：
(1) solid waste of mine can be all filled in short section working face, solved ground solid waste stacking and asked Topic, while having reached the not upper well requirement of downhole solid waste again, the cost of gangue treatment is reduced, is alleviated to ecological environment Damage, be conducive to the sustainable development of mine.
(2) after long section working face extraction, the short section working faces of both sides filling mining simultaneously, realize short face filling mining, The continuous mining system of long face high winning technology.
(3) it utilizes solid waste filling short section work face goaf to form tunnel, eliminates coal column, improve returning for resource Yield.
