Abstract
The invention discloses a method for filling paste behind filling hydraulic supports. The method comprises the steps of (1), separating two adjacent hydraulic supports and taking a rear telescopic girder, so that back ends of top beams of the hydraulic supports are separated from a top plate; (2), adding flame-retardant sponges tosides of back baffles, placing flame-retardant sponges in gaps between back ends of the top beams and the top plate, lifting the back ends of the hydraulic supports to enable the flame-retardant sponges to be clamped between the top beams and the top plate, and controlling a side-pushing jack to seal the two hydraulic supports; (3) placing waste non-flammable adhesive tapes in gaps between the top plate and the back baffles, and placing lower ends of the waste non-flammable adhesive tapes in gaps between a bottom plate and the back baffles; (4) forming a separation wall between the back of the hydraulic supports and an area to be filled to completely seal the space to be filled; (5), filling the space to be filled with paste from top to bottom, removing the hydraulic supports after a filling body solidifies and meets requirements for support force, and performing the next filling. Materials used in the method are the flame-retardant sponges and the waste non-flammable adhesive tapes, the materials are cheap, the operation process is simple, and the implementation is easy.
Description
Technical field
The present invention relates to a kind of paste body filling method after filling hydraulic support frames.
Background technology
Along with the scarcity of superficial part coal resources, Part Coal Mine has entered railways and water-bodies, i.e. coal mining, coal mining under water bodies under coal mining underbuildings, railway.Railways and water-bodies has higher requirements to controlling ground settlement, thereby generally adopts complete filling mining method.Paste body filling has controls that effect of settling is good, operating procedure is simple and economically viable advantage, but at present mostly the ubiquitous problem of paste filling hydraulic bracket be: between support, seal is bad, and support and top board can not connect reality fully.For fear of the easy running pulp problem of filling and injecting slurry, generally adopt packed filling after the conventional bracket frame, when inclined shaft or stope filling, slurries hang down to pressing and are easy to filling bag is damaged by pressure, both waste filler, polluted again the stope environment, especially had a strong impact on coal mining efficient, can't enrich the goaf in addition fully and cause filling effect not good, can't realize the Optimal Control to ground settlement.
Summary of the invention

(4) the hydraulic support rear with treat the filling area form together with divider wall, the filling space is treated in sealing fully;
(5) fill from top to bottom lotion, solidify until obturation and remove hydraulic support after satisfying the support force requirement, carry out next filling.
In described step (2), flame-retardant sponge is fixed on the side of backboard by thin wire.
Described backboard is provided with four, is respectively top left side backboard, right side, top backboard, left side, below backboard, downside right side backboard.
The present invention includes following steps:
(1) with adjacent two hydraulic supports separately, extensible canopy after regaining makes the hydraulic support top beam rear end separate with top board, falls left side, top backboard, right side, top backboard, mentions left side, below backboard, downside right side backboard;
(2) increase flame-retardant sponge in the backboard side, between top beam rear end and top board, flame-retardant sponge is placed in the gap, rise the hydraulic support rear end flame-retardant sponge be clamped between back timber and top board, control the thruster jack, make two hydraulic supports sealings;
(3) waste and old non-flammable adhesive tape is put into gap between top board and top left side backboard, right side, top backboard, rise left side, top backboard, right side, top backboard, waste and old non-flammable adhesive tape is clamped between top board and top left side backboard, right side, top backboard, waste and old non-flammable adhesive tape lower end is placed on base plate and left side, below backboard, in gap between the backboard of downside right side, fall left side, below backboard, downside right side backboard, waste and old non-flammable adhesive tape lower end is clamped in base plate and below left side backboard, between the backboard of downside right side;
(4) the hydraulic support rear with treat the filling area form together with divider wall, the filling space is treated in sealing fully;
(5) solidify until obturation and remove hydraulic support after satisfying the support force requirement, carry out next filling.
Beneficial effect of the present invention: there is following advantage in the present invention with respect to prior art:
1, take traditional lotion filling method as the basis, further improve perfectly, made up the easy running pulp of traditional filling method, the drawback of complicated operation;
2, material therefor is flame-retardant sponge and waste and old non-flammable adhesive tape, and material price is cheap;
3, operating procedure is simple, easily implements;
4, improve filling effect, thereby improve pack effectiveness, for efficient the coal mining creates conditions;
5, can enrich the goaf fully, realize the Optimal Control to ground settlement;
6, create good filling environment, for safety work provides the safe space, significantly alleviate labor strength.
