Abstract
The present invention discloses a kind of spoil zero-emission short face without coal pillar mining method, suitable for being used during mine spoil zero discharge treatment.According to actual condition of mines, in pitshaft arrangement short section working face in a region selected around, using adopt entirely fill entirely by the way of short section working face is exploited, the waste filling that produces in mine other exploitation working faces is entered into shortwall, shortwall carries out staying lane along filling face edge and the supporting of entity coal side anchor pole, utilizes the exploitation for staying lane to carry out Adjacent Working Face.The present invention mainly replaces coal body by spoil, realizes the maximization of the utilization of resources, at the same again can complete controlroof, realize that lossless melt of rock stratum is adopted, application value is high.
Description
Technical field
The present invention relates to a kind of spoil zero-emission short face without coal pillar mining method, mine spoil zero discharge treatment is particularly suitable for
When use.
Background technology
China's coal-mine produces more than one hundred million tons of spoil per annual meeting, and the major way of the spoil of colliery processing now is exactly outdoor heap
Put, so that substantial amounts of soil can be taken, not only pile things on or destroy original landforms vegetation, and air storage can be easy to from
Combustion, noxious material can all cause serious harm to environment for human survival and mining area ecological environment caused by spontaneous combustion.
China has explored the mode of a variety of processing spoils, but is all that colliery first emits spoil mostly, then
It is utilized, although therefrom having handled part spoil, while a large amount of dust is also produced in discharge and processing procedure, to environment
Secondary pollution is caused, is currently badly in need of a kind of coal-mining method of downhole gangue zero-emission.
The content of the invention
Technical problem：The purpose of the present invention is overcome the shortcomings of in prior art, there is provided a kind of method is simple, realizes effect
Good and sound spoil zero-emission short face is without coal pillar mining method.
Technical solution：A kind of spoil zero-emission short face is without coal pillar mining method, it is characterised in that step is as follows：
A. according to actual condition of mines, shortwall is being set near mine shaft station, shortwall exploitation
Exploited apart from shaft station 500m~1000m, shortwall to the direction away from shaft station initial position；
B. by mine, other are exploited the spoil produced in working faces and all transport to shortwall, and shortwall is used and is adopted entirely
The mode filled entirely is exploited, using spoil to shortwall filling mining, while during exploitation to back and
Side wall carries out suspension roof support, and suspension roof support includes filling the supporting of face edge and in entity coal side supporting along shortwall, and
Formed after supporting on the outside of shortwall and stay lane, while the digging laneway on the outside of the adjacent shortwall of current shortwall；
C. after tunnelling is complete, open-off cut is tunneled from tunnel to current shortwall, using staying lane and adjacent driving
The filling mining working face that tunnel forms adjacent shortwall is continued to be exploited in a manner of Quan Caiquan fills and is returned using spoil
Fill out, while shift adjacent tunnel and open-off cut that heading equipment tunnels next shortwall, opened for ensuing shortwall
Adopt and prepare；
E. repeat step b and c, so as to fulfill the continuous exploitation of the shortwall of mine processing spoil, until handling completion
All spoils of lower generation, realize the zero-emission of ground spoil.
The shortwall is used for underground storage spoil, and shortwall width is 30~50m, is highly coal seam height,
Length is 1000m~3000m.The lanewidth degree that stays is 3~6m.The shortwall mining sequence is protrusive with retreating
Alternately, tunnelling order is protrusive always to formula.
Beneficial effect：By adopting the above-described technical solution, the present invention has the following advantages that compared with prior art：
(1) solid waste such as all spoils produced in progress of coal mining are by backfilling directly in down-hole treatment, nothing
Ground need to be discharged into again, realize the target of spoil zero-emission, avoid spoil discharge and caused by environmental pollution, while significantly
Degree reduces the cost of floor treatment spoil.
(2) shortwall exploitation only needs the filling hydraulic support of small-sized coalcutter and ten framves or so, avoids mine
The input of high cost, and overcome that production efficiency caused by current filling technique is low, delays the problem of normal production.
(3) shortwall filling mining Hou Liu lanes, reduce tunnelling, reduce the cost of tunnelling.
(4) coal body is replaced by spoil, while eliminates coal column, realize the maximization of the utilization of resources, shortwall is complete
Adopt it is complete fill again can complete controlroof, realize that lossless melt of rock stratum is adopted, application value height.

Embodiment
One embodiment of the present of invention is further described below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, spoil zero-emission short face of the invention is without coal pillar mining method, it is characterised in that step is as follows：
A. according to actual condition of mines, shortwall 1, the shortwall are being set near mine shaft station
1 is used for underground storage spoil, and shortwall width is 30~50m, is highly coal seam height, length is 1000m~3000m, short
Opened apart from shaft station 500m~1000m, shortwall 1 to the direction away from shaft station the initial position of working face mining
Adopt, sequentially for protrusive and retrusive alternately, the shortwall 1 tunnels 1 working face mining of shortwall
Order is protrusive always；
B. by mine, other are exploited the spoil produced in working faces and all transport to shortwall 1, to shortwall 1 using complete
Adopt the mode filled entirely to be exploited, using spoil to 1 filling mining of shortwall, while to back during exploitation
Suspension roof support is carried out with side wall, suspension roof support includes filling the supporting of face edge and in entity coal side supporting along shortwall 1, and
Being formed after supporting in the outside of shortwall 1 and stay lane 2,2 width of lane that stays is 3~6m, while in current shortwall 1
Adjacent 5 outside digging laneway 3 of shortwall；
C. after having been tunneled after tunnel 3, open-off cut 4 is tunneled from tunnel 3 to current shortwall 1, using staying lane 2 and adjacent pick
Into tunnel 3 form the filling mining working face of adjacent shortwall 5 and continue in a manner of Quan Caiquan fills to be exploited and utilized
Gangue refill, while adjacent tunnel 6 and open-off cut 4 that heading equipment tunnels next shortwall are shifted, it is ensuing short
Working face mining is prepared；
