Definitions
- the invention relates to a clean and efficient coal mining method, and is particularly suitable for the field of mine solid waste treatment.
- coal mining companies have also proposed ways to comprehensively use, such as solid waste power generation, production of building materials, recycling of beneficial mineral products, production of chemical products, improvement of soil, production of fertilizers, backfilling (including building backfilling, filling of lowland and wasteland, Filling the mine goaf, reclaiming the coal mine subsidence area, building roads, etc., but can not completely solve the problem of solid waste treatment.
- solid waste power generation production of building materials
- recycling of beneficial mineral products production of chemical products
- improvement of soil production of fertilizers
- backfilling including building backfilling, filling of lowland and wasteland
- Filling the mine goaf reclaiming the coal mine subsidence area, building roads, etc.
- the object of the present invention is to overcome the deficiencies in the prior art and to provide a clean and efficient coal mining method that not only rapidly processes ground solid waste but also achieves downhole solid waste without raising well.
- the clean and efficient coal mining method of the present invention is characterized in that it comprises the following steps:
- the long-segment working face for filling the solid waste of the mine is arranged, and the short working face I and the short working face II are respectively arranged on both sides of the long working face, and the width of the short working face is arranged as w Debugging the shearer, hydraulic support and belt conveyor equipment in the short section working face I and the short section working face II, simultaneously mining the short section working face I and the short section working face II, and discarding the solids of the existing mine in the mining Filling the coal gangue produced in the mining and mining, and anchoring the edge of the filling surface and the solid coal side to retain the retaining road on both sides of the filling surface;
- the excavator is used to excavate the open cut between the short working face I and the short working face II, so that the short working face I and the short segment
- the remaining roadway and the open cut hole under the working face II constitute a long section working face mining system
- the specific size is determined by the amount of solid waste Q.
- l is the length of the short section and h is the short section.
- All of the long working faces have a width of 150m to 300m.
- the width of the roadway retained after the short section working surface is filled is 4-6 m.
- the present invention Since the above technical solution is adopted, the present invention has the following advantages compared with the prior art:
- the solid waste of the mine can be filled into the short section of the working face, which solves the problem of stacking solid waste on the ground, and at the same time achieves the requirement that the underground solid waste does not go to the well, reduces the cost of the meteorite treatment, and reduces the ecological Environmental damage is conducive to the sustainable development of the mine.
- FIG. 1 is a schematic view of a clean and efficient coal mining method of the present invention.
- the clean and efficient coal mining method of the present invention comprises the following steps:
- a long working face 21 for filling the solid waste of the mine in the coal seam of the mine shaft the long working face width is 150m-300m, and the short working face I11 is arranged on both sides of the long working face 21 respectively
- l is the length of the short working face
- h is the mining height of the short working face
- the shearer, hydraulic support and belt conveyor equipment in the short working face I11 and the short working face II12 are debugged, and the short section work is simultaneously mined.
- the excavator is used to excavate the opening and cutting eye 4 between the short section working surface I11 and the short section working surface II12, so that the short section working surface I11 is short.
- the remaining roadway 31 and the open cut eye 4 retained by the section working face II12 constitute a long section working face mining system;
