Abstract
The invention provides a method for fully mechanized continuously-filling coal mining of steeply pitching coal seams, which comprises the following steps: a stoping face is arranged as per the method of long-wall mining along the strike, and fully mechanized mining equipment for the steeply pitching coal seam is adopted; an air cushion and a working face filling pipeline are arranged on a base on the side of a mined out space of rear pillars of a fully mechanized mining support; whenever the working face advances for every 1.4 to 1.8 meters and after the support is moved, the working face filling pipeline is connected with an upper gateway filling main pipeline; the air cushion is filled with air, and auxiliary separation is arranged; paste is conveyed to a filling pipe branch sequentially from low to high so as to ensure filling and compacting, and finally the paste is conveyed to a supplementary filling pipe of the upper gateway; after the paste is coagulated, a portion of air in the air cushion is released, and the working face advances forward continuously; the steps are repeated until the stopping work for the whole working face and the filling work for the mined out space are finished. The method provided by the invention is convenient to operate and simple to carry out, can improve the mechanization level for mining the steeply pitching coal seams under buildings, railways and water bodies, improves the output of the working face, efficiently reduces the roof subsidence and the ground deformation, and realizes coal mining without the pillars and achieves Y type ventilation.
Description
Technical field
The present invention relates to the goaf filling exploitation method of a kind of colliery pit mining, particularly a kind of half-edge coal seam is combined the continuous filling coal mining method of adopting.
Background technology
Along with China's economy and fast development of society; Coal high strength exploitation for many years; The coal seam is fewer and feweri preferably to make mining area, Eastern China and superficial part occurrence condition; Thereby make " three times " press the research of the mining problem of coal and half-edge coal seam to get into important stage, cause the great attention of scientific circles and enterprise.High-dipping or high inclination-angle coal reserves account for about 15%～20% of national coal reserves, and particularly western part and the southern most mine in China all has half-edge coal seam, and half-edge coal seam is the main mining coal seam of many mining areas or mine.
In recent years, the research work of the gentle inclined cut of high-dipping fully-mechanized mining equipment filling mining has been obtained bigger progress, but very few to combining the half-edge coal seam filling mining research of adopting under the condition.The general employing of high-dipping filling mining faced upward the slanted bar band method of collecting coal by the means of filling, in next working face extraction on the goaf of a work plane carry out spoil from slipping filling, or in this working face extraction, carry out spoil from slipping filling; But this method coal winning technology falls behind, and labor strength is big, and the pillar consumption is big; Roof stability is poor, and safety factor is low, and the goaf filling compactness is not high; Loosely organized, cause surface deformable big, the protection of the face of land being protected object is limited.
Summary of the invention
In order to solve the above-mentioned technical problem that existing half-edge coal seam filling mining exists, the present invention provides a kind of half-edge coal seam to combine the continuous filling coal mining method of adopting.The present invention can improve the mechanization level of steeply-inclined seam mining, significantly improves work plane output, improves the work plane condition; Reduce labor strength, can solve problems such as roadway surrounding rock pressure is big, can effectively control surface deformable; Solve the difficult problem of half-edge coal seam " three times " exploitation; Can also realize not having coal pillar mining and Y type and ventilate, improve coal recovery rate, prevent and treat methane accumulation, leak out and Period of Coal Seam Spontaneous Combustion.In addition, the present invention can consume gangue, waste solid and flyash etc., environmental benefit, economic benefit and obvious social benefit.
The technical scheme that the present invention solves the problems of the technologies described above may further comprise the steps:
1) from the supreme crossheading of floor pavement filling main line pipeline;
2) work plane is installed coal-winning machine, scratch board conveyor, comprehensive mining hydraulic bracket and air cushion, the face filling pipeline of on the base between comprehensive mining hydraulic bracket rear column and air cushion, assigning a work, and following crossheading is installed elevating conveyor and scalable adhesive tape conveyor;
3) stope is whenever pushed ahead 1.4～1.8m, move frame after, work plane filling pipeline is connected with last crossheading filling main line pipeline;
4) charged pressure is that the gas of 0.5MPa expands air cushion in air cushion, forms the air cushion partition wall between row's fully-mechanized mining working and the goaf, and arranges auxiliary spacer assembly;
5) in the filling branched pipe of work plane low side, carry lotion; After treating that lotion connects the top and low end regions is filled with; Carry lotion to second filling pipe on top again; Construct with this, according to carrying out filling by low successively to high principle of temporal sequence, crossheading face end support place replenishes filling pipe and carries lotion on work plane at last;
6) after filling finishes, wash whole filling main line pipeline, work plane filling pipeline and ground Filling Station equipment and device;
7) treat that obturation condenses, the air cushion internal gas pressure is released into 0.3MPa, accomplish the circulation of a back production and filling;
8) work plane begins to push ahead, repeating step 3), 4), 5), 6), 7), accomplish the circulation of next back production and filling, so circulation is until back production and the filling operation of accomplishing entire working surface.
Technique effect of the present invention is:
1) the present invention adopts fully-mechanized mining equipment and filling air cushion to combine; Improve the mechanization level of " three times " steeply-inclined seam minings, enhanced productivity greatly, reduced working strength of workers; Can also effectively control face roof pressure, guarantee workman's safety;
2) the present invention carries out filling to the goaf, can effectively control ground settlement, reduces face of land disturbance, reduces roadway surrounding rock pressure, can also realize not having coal pillar mining and Y type and ventilate, and improves coal recovery rate, prevents and treats methane accumulation, leaks out and Period of Coal Seam Spontaneous Combustion.
3) goaf filling of the present invention also can consume a large amount of gangues, waste solid and flyash the like waste, turns waste into wealth, and has reduced it to the pollution of surrounding enviroment with to appropriation of land.
