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 enters railways and water-bodies, i.e. coal mining underbuildings, Gas burst, coal mining under water bodies.Railways and water-bodies has higher requirements to control ground settlement, thus the complete filling mining method of general employing.Paste body filling has that control settlement is effective, 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 completely.In order to avoid the easy running pulp problem of filling and injecting slurry, general employing is packed filling after conventional bracket frame, when inclined shaft or stope filling, slurries pressure of hanging down is easy to filling bag to damage by pressure, both wasted filler, and polluted stope environment again, especially have a strong impact on coal mining efficiency, in addition cannot enrich goaf completely causes filling effect not good, cannot realize the Optimal Control to ground settlement.
Summary of the invention
The object of the invention is to overcome the shortcoming of paste filling hydraulic bracket to goaf seal deficiency, provide one to have the simple and economically viable lotion backfill method of good seal, operating procedure.
Object of the present invention can be achieved through the following technical solutions:
A kind of paste body filling method after filling hydraulic support frames, is characterized in that, comprise the following steps:
(1) by adjacent two hydraulic supports separately, extensible canopy after regaining, makes hydraulic support top beam rear end be separated with top board;
(2) increase flame-retardant sponge in backboard side, between top beam rear end and top board, flame-retardant sponge is placed in gap, and rise hydraulic support rear end then flame-retardant sponge is clamped between back timber and top board, controls thruster jack, makes two hydraulic supports sealings;
(3) waste and old non-flammable adhesive tape is put into the gap between top board and backboard, rise backboard, waste and old non-flammable adhesive tape is clamped between top board and backboard, waste and old non-flammable adhesive tape lower end is placed in the gap between base plate and backboard, fall backboard, waste and old non-flammable adhesive tape lower end is clamped between base plate and backboard;
(4) hydraulic support rear formed with district to be filled together with divider wall, completely close space to be filled;
(5) fill lotion from top to bottom, body to be filled removes hydraulic support after solidifying and meeting support force requirement, carries 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 pieces, is upper left backboard, upper right backboard, lower left backboard respectively, backboard on the right side of downside.
The present invention includes following steps:
(1) by adjacent two hydraulic supports separately, extensible canopy after regaining, makes hydraulic support top beam rear end be separated with top board, falls upper left backboard, upper right backboard, mention lower left backboard, backboard on the right side of downside;
(2) increase flame-retardant sponge in backboard side, between top beam rear end and top board, flame-retardant sponge is placed in gap, and rise hydraulic support rear end then flame-retardant sponge is clamped between back timber and top board, controls thruster jack, makes two hydraulic supports sealings;
(3) waste and old non-flammable adhesive tape is put into the gap between top board and upper left backboard, upper right backboard, rise upper left backboard, upper right backboard, waste and old non-flammable adhesive tape is clamped between top board and upper left backboard, upper right backboard, waste and old non-flammable adhesive tape lower end is placed on base plate and lower left backboard, in gap between the backboard of right side, downside, fall lower left backboard, right side, downside backboard, waste and old non-flammable adhesive tape lower end is clamped in base plate and lower left backboard, on the right side of downside between backboard;
(4) hydraulic support rear formed with district to be filled together with divider wall, completely close space to be filled;
(5) body to be filled removes hydraulic support after solidifying and meeting support force requirement, carries out next filling.
Beneficial effect of the present invention: the present invention exists following advantage relative to prior art:
1, based on traditional lotion filling method, improve perfect further, compensate for 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, improving filling effect, thus improve pack effectiveness, creating conditions for efficiently mining;
5, goaf can be enriched completely, realize the Optimal Control to ground settlement;
6, create good filling environment, for safety work provides safe space, significantly alleviate labor strength.

Below in conjunction with concrete the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, one end of hydraulic support 1 contacts with coal body 8, and the opposite side of hydraulic support 1 is fill area 7, forms space 2 to be filled between fill area 7 and backboard 6.By adjacent two hydraulic supports 1 separately, extensible canopy 3 after regaining, adjustment jack, makes hydraulic support 1 back timber 4 rear end be separated with top board 5.Backboard 6 points four pieces, is respectively upper left backboard, upper right backboard, lower left backboard, backboard on the right side of downside.Fall upper left backboard, upper right backboard, promote lower left backboard, backboard on the right side of downside.
As shown in Figure 2, flame-retardant sponge 10 is increased in backboard 6 side, be fixed on backboard side with thin wire, between back timber 4 rear end and top board 5, flame-retardant sponge 10 is placed in gap, rise hydraulic support 1 rear end then flame-retardant sponge 10 is clamped between back timber 4 and top board 5, control thruster jack, two hydraulic supports 1 are sealed, waste and old non-flammable adhesive tape 11 is put into top board 5 and upper left backboard, in gap between upper right backboard, rise upper left backboard, upper right backboard, waste and old non-flammable adhesive tape 11 is clamped in top board 5 and upper left backboard, between upper right backboard, waste and old non-flammable adhesive tape 11 lower end is placed on base plate 9 and lower left backboard, in gap between the backboard of right side, downside, fall lower left backboard, right side, downside backboard, waste and old non-flammable adhesive tape 11 lower end is clamped in base plate 9 and lower left backboard, between the backboard of right side, downside.
As shown in Figure 3, divider wall together with hydraulic support 1 rear is formed with space 2 to be filled, closes space 2 to be filled completely, forms new filling lotion 12.Fill lotion from top to bottom, body to be filled removes hydraulic support after solidifying and meeting support force requirement, carries out next filling.
