Abstract
The invention discloses a method for filling a gas near a roadway of coal mine gob-side entry retaining, comprising the following steps: firstly, arranging a gas pressurization room on the ground; then, arranging a gas booster pump in an underground mining area haulage roadway 3; arranging a cylinder rubber air sac as high as the mining height on one side close to a goaf along the gob-side entry retaining behind a coal face; aerating the cylinder rubber air sac arranged on one side close to a goaf by the gas booster pump until roof contacting; when the pressure gage of the gas booster pump displays that the pressure reaches the stress of a primary rock, stopping aerating, sealing the cylinder rubber air sac to finish the aeration operation of one cylinder rubber air sac; and when the coal face is continuously advanced, continuously arranging one cylinder rubber air sac behind one aerated cylinder rubber air sac every time the coal face is advanced by one step, and aerating one by one until one exhausting body on one side of the goaf 5 along the gob-side entry retaining 6 is filled and supported. The method is simple, is convenient to operate and has the advantages of small labor intensity of workers and good supporting effect.
Description
Technical field
The present invention relates to the other gas filling method in a kind of coal mine gob-side entry retaining lane, be particularly useful for the other filling in coal mining work plane gob side entry retaining lane.
Background technology
Gob side entry retaining is after the upper curtate work plane is adopted, and through adding strong supporting or adopt other effective ways, a crossheading of upper curtate work plane is remained, and uses as a crossheading when supplying the lower curtate working face extraction.As the major reform of production practice, gob side entry retaining utilization rate abroad is higher, but technology popularization speed just at the early-stage at home is not high.Gob side entry retaining have improve the coal resources rate of extraction, reduce drivage ratio, alleviate alternately nervous between the digging back production, reduce the work plane removal charge, improve remarkable advantage such as safety production condition, be to fail to find suitable gob-side entry retaining support material but restrict the main cause that this technology promotes the use of in China.The roadside packing material of domestic main use at present has spoil, concrete lotion, high percentage of water rapid solidifying material etc.But these materials also come with some shortcomings in stowing operation, and, obturation not enough like obturation early anti pressured intension time of setting, oversize, filler difficulty of transportation, filling cost were high excessively.
Summary of the invention
The objective of the invention is to overcome the problem that exists in the prior art, provide that a kind of method is simple, the obturation early strength high, save support material, reduce the other gas filling method in coal mine gob-side entry retaining lane of labour intensity.
The other gas filling method in coal mine gob-side entry retaining of the present invention lane comprises the steps:
A., the gas boosting room is set near the auxiliary shaft of ground, in the gas boosting room, settles ground gas boosting pump and the high pressure tank that 0.8～1Mpa gases at high pressure are housed;
B. in the exploiting field haulage way of down-hole coal excavation work plane the place ahead 5～20m, arrange the mine gas booster pump that links to each other with ground high pressure tank pipeline;
C. when coal-face advance distance open-off cut 5～8m; A height and the highly identical cylinder rubber pneumatic bag of mining are laid near goaf one side in the empty tunnel that keeps on the edge at coal-face rear, and the diameter of cylinder rubber pneumatic bag and its ratio highly are 0.4～0.6;
D. by the road the empty tunnel that keeps, the edge that is laid in the coal-face rear is inflated near the cylinder rubber pneumatic bag of goaf one side through the mine gas booster pump, until connecing the top;
E. when the pressure meter of mine gas booster pump shows that pressure reaches the stress of primary rock, stop inflation, the cylinder rubber pneumatic bag is sealed;
F. along with coal-face is pushed ahead a step pitch, continue to lay a cylinder rubber pneumatic bag along the empty tunnel that keeps near goaf one side at the coal-face rear;
G. repeating step d, e, f constantly carry out the inflation of next row's cylinder rubber pneumatic bag, until accomplishing the gas filling supporting that keeps the tunnel near goaf one side along empty.
The described stress of primary rock=adopt deeply * the overlying rock body force; It is said that inflation is air or nitrogen to the cylinder rubber pneumatic bag.
Beneficial effect:
1) the present invention utilizes gases at high pressure to charge into rubber pneumatic bag to form obturation and carry out the supporting of gob side entry retaining roadside packing, and process links is few, and filling procedure is few, and labor strength is little, and produce influence to mining few.
2) obturation that forms has the early strength height, initiatively connects the advantage of top supporting roof, and the obturation internal pressure can increase and the characteristics of increase along with roof pressure, has better supporting effect.
3) only need in the main tunnel of mine, to lay gas pipeline, filling gas can be carried in the pipeline high speed, and cost of transportation is low, has reduced worker's labour intensity.
4) through gas filling, improve coal recovery rate, reduced the tunnelling rate, increased economic benefit.

The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
The other gas filling method in coal mine gob-side entry retaining of the present invention lane at first is provided with the gas boosting room near the auxiliary shaft of ground, in the gas boosting room, settle ground gas boosting pump and the high pressure tank that 0.8～1Mpa gases at high pressure are housed; In the exploiting field haulage way 3 of down-hole coal excavation work plane 1 the place ahead 5～20m, arrange the mine gas booster pump 4 that links to each other with ground high pressure tank pipeline then; When coal-face 1 advance distance open-off cut 5～8m; A height and the highly identical cylinder rubber pneumatic bag 2 of mining are laid near goaf 5 one sides in the empty tunnel 6 that keeps on the edge at coal-face 1 rear, and the diameter of cylinder rubber pneumatic bag 2 and its ratio highly are 0.4～0.6; By the road to being laid in inflating near the cylinder rubber pneumatic bag 2 of goaf 5 one sides along the empty tunnel 6 that keeps of coal-face 1 rear, until connecing the top, 2 inflations are air or nitrogen to the cylinder rubber pneumatic bag through mine gas booster pump 4; When the pressure meter of mine gas booster pump 4 shows that pressure reaches the stress of primary rock, stop inflation, cylinder rubber pneumatic bag 2 is sealed, accomplish the inflation of a cylinder rubber pneumatic bag 2; The stress of primary rock=adopt deeply * the overlying rock body force.Along with constantly pushing ahead of coal-face 1; Whenever push ahead a step pitch; After the cylinder rubber pneumatic bag 2 that inflation is before accomplished, continue to lay a cylinder rubber pneumatic bag 2; And inflation one by one, until accomplishing an exhaust body filling and support that keeps tunnel 6 near goaf 5 one sides along empty.
