Abstract
The invention relates to a coal mining method for a high-dipping low coal seam by long-wall mining. The method comprises the following steps of: supporting a roof by a self-advancing air bag support; arranging a working surface in a mode of advancing to the dip; mining coal by drilling and blasting or using an off-pan shearer; transporting the coal in a mode of gravity haulage; filling a goaf with gangue or sand; and filling a lower end with gangue bags, precast concrete blocks or solidified macromolecular foaming slurry. The coal mining method has the advantages of realizing mechanical coal mining for the high-dipping low coal seam, improving the yield per unit and efficiency of the working surface, effectively protecting the exploited ground, improving the recovery rate of mines, and guaranteeing the coal seam mining safety.
Description
Technical field
The present invention relates to a kind of coal-mining method of moving towards the broadwall steeply inclined thin seam.
Background technology
The coal-mining method that steeply inclined thin seam is commonly used is: warehouse style coal-mining method, the intensive coal-mining method of horizontal fragmentation, overhand mining, little stage coal-mining method etc.Wherein, warehouse style coal-mining method and little stage coal-mining method are forbidden by country's order; The labour intensity of intensive coal-mining method of horizontal fragmentation and overhand mining is big, and effect is low, and is dangerous, can't realize mechanical mining.
Summary of the invention
The invention provides a kind of novel coal-mining method, can realize the mechanization or the semi-mechanization exploitation of steeply inclined thin seam, the output and the efficient of work plane improve greatly, and safety in production is guaranteed.
This method adopts a kind of novel gas that moves certainly to pile up neatly bracket support in work plane, the work plane lower end adopts the supporting of cross sliding type end hydraulic support, drill and blast or the coal-winning machine coal breakage, handle the goaf with whole fill or part filling method, headentry adopts the roadside packing edge air gallery technology, realizes the mechanization or the semi-mechanization exploitation of steeply inclined thin seam with this.When moving the control of gas buttress support employing electro hydraulic valve certainly, can realize work plane automated mining.
In order to realize that steeply inclined thin seam moves towards the mechanization of broadwall, primary problem is to realize the mechanization of face timbering.The present invention adopts a kind of novel gas buttress support that moves certainly to carry out face timbering, and the work plane lower end has been realized the mechanization of supporting with the supporting of two cross sliding type end hydraulic supports.As prerequisite, can further realize the mechanization of work plane coal breakage.The filling method in work plane goaf is handled, and not only can slow down the mine pressure of work plane, and can slow down ground settlement, reaches the purpose of protection above ground structure.The roadside packing edge air gallery technology not only can reduce the drivage ratio of steeply inclined thin seam, and can improve the resource recovery of mine.
The technical solution adopted for the present invention to solve the technical problems is: moving towards in the coal wall that a puppet is bowed and tiltedly arranged, according to face length, certainly the gas that moves of layout some is piled up neatly support, with emulsion and pressure wind is support power, each circulation support crossbeam of moving one's steps is established a step pitch for supporting to reach, arrange two cross sliding type end hydraulic supports in the transportation lane of work plane lower end, each circulation is established a step pitch to reach equally.Work plane adopts and drills and blasts or the off pan shearer coal breakage, and the coal that falls transports in slide mode certainly.The work plane goaf is carried out filling along with the propelling of work plane with spoil or sand.At the work plane lower end,, solidify with spoil bag or precast concrete block, macromolecule foaming slurries and to carry out filling along with the advance of the face.
The invention has the beneficial effects as follows, can realize the steeply inclined thin seam mining mechanization, improve the per unit area yield and the efficient of work plane, and protection of the ground that can effectively exploit and raising mine resource recovery, the safety that steeply inclined thin seam is exploited guaranteed.
Description of drawings
Fig. 1 is the plan view that present device is arranged;
Fig. 2 is the sectional drawing that present device is arranged.
1 from moving gas buttress support among the figure, 2 coal-winning machines, 3 beams of moving one's steps, 4 working face walls, 5 tailentries, 6 air compressor machines, 7 suspention jack, 8 anchoring columns, 9 emulsion power packs, 10 headentries, 11 crossheading drag conveyor or elevating conveyors, 12 cross sliding type end hydraulic supports, 13 pedestrian's ladders, 14 roadside packing bodies, 15 goaf filling bodies.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
In Fig. 1 and Fig. 2, coal-winning machine 2 prescinds rib 4 the circulation step pitch of a work plane earlier along the rack rails coal breakage of the beam 3 of moving one's steps, and the beam 3 of will moving one's steps then pushes away a step pitch forward, is support with the beam 3 of moving one's steps again, in order gas is piled up neatly support 1 and is established a step pitch to reach.The beam 3 of moving one's steps is held by the suspention jack 7 that is located in the tailentry 5, can be in case beam 3 downslides of moving one's steps; Suspention jack 7 is by 8 anchorings of anchoring column.Along with the propelling of work plane, carry out goaf filling from the return airway 5 of work plane.In the work plane lower end,, carry out roadside packing along headentry 10 along with the advance of the face.
Install the cross sliding type end hydraulic support 12 in headentry 10,, establish a step pitch to reach prior to moving gas buttress support 1 certainly along with the propelling of work plane; Under the shielding of cross sliding type end hydraulic support 12, finish roadside packing.
Claims (3)
1. a coal-mining method of moving towards the broadwall steeply inclined thin seam is characterized in that, cross sliding type end hydraulic support 12 is used at two ends, the middle use from moving 1 supporting of gas buttress support, and production practice is:
(1) uses the rack rails coal cutting wall of coal-winning machine 2, finish a circulation along the beam 3 of moving one's steps;
