Description
Technical field
The present invention relates to technical field of coal exploitation, more particularly to a kind of solid material filling coal mining gob-side entry retaining method.
Background technology
Within the current and foreseeable some time from now on, coal can be the topmost energy of China.Coal in China yield
About 90% be pit mining, underground coal exploitation not only breaks up mining area ecological environment, infringement earth's surface buildings or structures, also association
Serious potential safety hazard, and the fundamental solution for solving these problems is that split mined out is filled.Existing filling is adopted
Coal method can further classify from used filler, be respectively：Solid material filling, ointment material filling, height
Water material filling.Solid material filling method, which is mined, can effectively liberate " under three " pressure coal, improve the recovery ratio of coal resources.Together
When, solid material filling method, which is mined, can make full use of gangue, mine tailing, urban solid garbage etc. as filler, reduce
The destruction of ground land resource, while reducing environmental pollution, improving mining area ecological environment.Adopted in current solid material filling method
In coal technology, when needing gob side entry retaining more than lane is stayed using high-water material or ointment material.When progress stays the lane to work, Xian Liu lanes
Location arrangements section is trapezoidal or rectangle filling pocket, then to filling pocket injection high-water material or ointment material, Gao Shui
Formation cross-section is trapezoidal or rectangle supporter after material or ointment material solidification.Supporter with higher-strength, will be left behind
Tunnel and fill area separate, complete a step supporter operation.Solid material packing job is carried out after one step supporter operation.
The work of the above is so repeated, complete whole solid material filling method coal mining stays lane to work.This simple use high-water material
Or ointment material stays the technique in lane can not effectively connect top, filler price is higher, also needs to use in stowing operation and fills
Filler bag, thus add cost.Research it is cheap, can effectively connect top solid material filling method mine stay lane work
Skill, it is significant.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of solid material filling coal mining gob-side entry retaining method, and it can be with
It is simple when solving solid material filling to stay lane effectively to connect top using high-water material or ointment material, use filling pocket cost
The problem of height, inefficiency.
In order to solve the above technical problems, the technical solution used in the present invention is realized by following steps：
（One）Working face fortune coal road, solid filling material lane and the digging for cutting eye
Digging work face transports coal road, solid filling material lane and cuts eye first, forms back production and the ventage of working face
System；
（Two）Mine and solid material stowage unit sets up and completes the coal work of certain distance
Set up and mine and solid material stowage unit, including be accompanied with the filling coal mining hydraulic support of pressing device, mine
Machine, fortune coal scratch board conveyor, fortune coal belt, solid filling material belt, solid filling materials scraper transporter, equipment have been set up
Bi Hou, starts to mine, working face is pushed ahead, forms the goaf that can be filled；
（Three）Stay the laying of lane isolation baffle plate
Lane isolation baffle plate is stayed in laying on the inside of the filler lane in goaf, is isolated in filler lane Ce Biyuliu lanes and is kept off
Horizontal pillar is set to stay lane isolation baffle plate for support between plate；
（Four）Stay the laying of lane stowage unit
Stay lane stowage unit is interconnected including staying stay lane to fill transverse tube, stay lane filling inclined tube, tunnel filling pipe and stay
Lane fills pump, and close to staying the inside bottom of lane isolation baffle plate to set tunnel filling pipe, tunnel filling pipe top is set to exploitation
Direction back sweep stays lane to fill inclined tube, stays what lane filled that inclined tube rear sets some horizontal distributions to stay the lane to fill transverse tube, lane
Road filling pipe is connected with staying lane to fill pump；
（Five）Solid material is filled
To staying the goaf on the inside of the isolation baffle plate of lane to carry out the solid material filling operation of certain distance；
（Six）The solid filling material close to isolation baffle plate is reinforced using fluid-filled material
With stay lane fill pump by fluent material by tunnel filling pipe, stay lane to fill inclined tube, stay lane to fill transverse tube to solid
Injected inside filler, the solid filling material that isolation baffle plate is will be close to after fluent material solidification is combined as a whole, and is formed
Stay lane supporter；
（Seven）Circulation exploitation
Repeat the（Three）Step is to the（Six）The work of step, completes the coal mining of next circulation and stays lane filling operation, successively
Analogize the coal mining for completing whole working face and stay lane filling operation.
It is used as the further improvement of the technical program, the step（Four）Stay lane fill transverse tube for punching pipe, stay lane
Fill and valve is installed on inclined tube insertion top plate certain altitude, tunnel filling pipe.
Compared with prior art, the present invention is then adopted using staying lane isolation baffle plate filler is separated with reserved tunnel
The mode that combination fluid reinforcing is filled with solid material completes to stay lane operation, it is to avoid simple to be stayed using high-water material or ointment material
The problem of lane technique effectively can not connect top, stays lane isolation baffle plate using horizontal pillar support, and Shi Liu lanes isolation baffle plate can not be to pre-
Stay prominent inside tunnel, the tunnel structure left is consolidated；Without using filling pocket, fluid-filled materials'use amount is reduced,
Reduce filling coal mining cost.
