Greatly, the shortcomings that owing to connect big top amount, filling effect difference；Increase reinforcement mechanism, improve pack completeness, but tamp complex process, drop
Low back production efficiency, and unmanageable influence of the solid waste to underground environment of above-mentioned filling coal mining method.
The content of the invention
Technical problem：For problem above, it is an object of the invention to provide a kind of solid waste to pack filling coal mining side
Method, overcome the shortcomings of to tamp complex process in prior art, there is provided a kind of method is simple, easily operated, and water isolating is good, adopts
Dead zone spoil bag stacks neat, support effect stabilization, the good goaf solid waste pack placement method of filling effect.
Technical scheme：A kind of solid waste packs filling coal mining method, wherein：
(1) since open-off cut, start suspension filling bag in tunnel side, its front portion is hung in filling coal mining liquid successively
After pressure support at back timber, in front of bottom-dump drag conveyor, rear portion is fixed on goaf rear portion top plate；
(2) filling bag on the outside of set up rely on filling hydraulic support plank fix；
(3) by be suspended on filling hydraulic support rear bottom-dump drag conveyor discharge port into filling bag according to
Secondary blanking filling, until being full of；
(4) after blanking is full of in bag to be filled, the steel wire lock of sack installation is tensed, sack is sealed, carries out next fill
Fill out the blanking filling of bag；
(5) repeat step (3), (4), it is complete it is in a row filling bag packing job after, dismounting rely on filling hydraulic support
Plank, by this row filling bag fixed with connect band；It is adjacent to front-seat filling bag, repeat step (1), (2), (3), (4), under completion
One row fills the packing job of bag；
(6) front two rows filling bag is fixed with connect band, repeat step (1), (2), (3), (4), (5), gone round and begun again,
Complete the filling in whole goaf.
The length of the filling bag is 2~4 filling hydraulic pressure support widths, is 3m~6m, and width is a unit advance,
It is highly identical with working face mining height for 0.6m~0.8m.
The filling bag uses polypropylene woven cloth, has good water isolating.
Fixed between the filling bag with connect band.
The filling bag passes through the tight sack of cable-type padlock padlock installed in sack after the completion of filling.
The solid waste includes gangue, flyash, building waste etc., and filler size grading is not more than
30mm。
Beneficial effect：The invention discloses a kind of solid waste to pack filling coal mining method, is consolidated using filling bag
The pack filling of body discarded object, solid pack obturation directly support goaf top plate, reach control movement, reduce
The purpose of surface subsidence.The filling coal mining method eliminates the complicated compacting technique of reinforcement mechanism, the solid dress being connected as a single entity
Bag obturation has strength and stable enabling capabilities to roof and filling bag water isolating is good, is easy to solid waste
Seal buried processing.Present invention process is simple, easy to operate, and filling effect is good, is advantageous to environmental protection, has extensive practical
Property.

Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
The present invention a kind of solid waste pack filling coal mining method, it is characterised in that comprise the following specific steps that as
Under：
(1) since open-off cut, start suspension filling bag 1 in tunnel side, its front portion is hung in filling coal mining successively
After hydraulic support at back timber 12, the front of bottom-dump drag conveyor 3, rear portion is fixed on goaf rear portion top plate；
(2) plank 15 that filling coal mining hydraulic support 2 is relied in the outside erection of filling bag 1 is fixed；
(3) by be suspended on the rear of filling coal mining hydraulic support 2 bottom-dump drag conveyor 3 discharge port 4 to filling
The interior blanking successively filling of bag 1, until being full of；
(4) after blanking is full of in bag 1 to be filled, the steel wire lock 14 of sack installation is tensed, sack is sealed, carries out next
Fill the blanking filling of bag 1；
