Abstract
The invention discloses a speedy tunneling method for a gas drainage roadway. The speedy tunneling method comprises the following steps: tunneling a return air inclined shaft, a rail inclined shaft and a transportation inclined shaft from the ground, and then respectively digging an return air stone door, a rail stone door, a rail gate way and a transporting stone door in positions respectively corresponding to the return air inclined shaft, the rail inclined shaft and the transportation inclined shaft; exploiting a measure shaft haulage tunnel and a measure well return air haulage tunnel, and then digging auxiliary cutting holes, a part of cutting holes, and a measure shaft gas lane so as to form a ventilation circuit and a transportation system; at the moment, the measure shaft haulage tunnel digs a base plate gas lane through the measure shaft gas lane; simultaneously digging into the base plate gas lane from the rail inclined shaft through the rail gate way, namely, the two ends simultaneously dig the base plate gas lane until the base plate gas lane is through, and the base plate gas lane and the measure shaft haulage tunnel form a gas drainage roadway circuit. The speedy tunneling method can be used for digging the gas drainage roadway quickly, realizes mine safe production, extraction and production, and produces more economic and social benefits.
Description
Technical field
The present invention relates to a kind of mine gas drainage tunnel method for digging, specifically a kind of speedy drivage method of gas drainage under suction tunnel.
Background technology
China is big coal country, and coal is the main energy sources of China's economic development; But China is also one of country that Gas Disaster is the most serious in the world, and wherein colliery is over half is high gas and outburst mine, and therefore Gas Disaster serious threat is to the safety in production in colliery simultaneously.
At present, the gas drainage technique (for rice square-bottomed bamboo basket colliery) in colliery is from ground driving transport, track and return air three inclined shafts, then at track inclined shaft corresponding position digging track gallery, and then tunnel base plate gas lane or the roof gas tunnel, namely excavate a gas drainage under suction loop, just can draw out methane for shaft production is prepared.But this method for digging causes tunneling gas lane process to be crossed and generally needs 1-2 slowly, and only after excavating gas lane completely, track gallery and haulage way could be tunneled, finally form stope to mine, so will greatly postpone the operation progress of mine, finally affect colliery benefit.
As from the foregoing, the mine development method drawn out methane if followed conventional lines, gas drainage under suction lane is then caused to be tunneled delayed, track gallery and haulage way is caused to tunnel delayed, mine will be postponed go into operation, therefore be necessary to improve the existing mine development method drawn out methane, under the prerequisite of mine safety production, realize going into operation in advance to produce larger economic benefit and social benefit.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of speedy drivage method of gas drainage under suction tunnel, can excavate fast gas drainage under suction tunnel, realize mine safety production and extract going into operation, produce larger economic and social benefit further.
To achieve these goals, the present invention includes following steps:
A: from ground driving return air inclined shaft, track inclined shaft and transport inclined shaft, then digs windstone gate, digs track crossdrift and track gallery in the position that track inclined shaft is corresponding, digs haulage cross-cut in the position that transport inclined shaft is corresponding in the position that return air inclined shaft is corresponding;
B: open up two footrills on border, field with "nine squares": service shaft haulage tunnel and service shaft return air footrill, then excavates and auxiliary cuts eye, a part cuts eye, service shaft gas lane, forms ventilation circuit and transportation system;
C: now service shaft haulage tunnel is by driving base plate gas lane, service shaft gas lane; Simultaneously from track inclined shaft through track heading base plate gas lane, namely to tunnel base plate gas lane through to base plate gas lane simultaneously at two ends, and through rear base plate gas lane and service shaft haulage tunnel form loop, gas drainage under suction tunnel;
D: excavate next by service shaft gas lane and adopt gas lane, face, prepares for next face of adopting draws out methane in advance.
Compared with the mine development method drawn out methane with routine, the present invention has following effect:
(1) base plate gas lane can just be tunneled from service shaft haulage tunnel by service shaft gas lane, simultaneously from track inclined shaft through track heading base plate gas lane, so just can tunnel base plate gas lane in two ends simultaneously, shorten the gas tunnelling time greatly;
(2) need not excavate loop, gas drainage under suction lane again after base plate gas lane is through, directly extract out from service shaft haulage tunnel, this can reduce the engineering quantity of about half, draws out methane in advance to coal seam; Shorten loop, reduce flowing resistance, realize safety and go into operation in advance, produce great economic benefit and social benefit;
(3) the base plate gas lane that next adopts face can be excavated from measure gas lane simultaneously, prepare for next face of adopting draws out methane in advance, realize mine safety and produce in advance.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the speedy drivage method in gas drainage under suction tunnel of the present invention, comprises the following steps:
A: from ground driving return air inclined shaft 1, track inclined shaft 2 and transport inclined shaft 3, then digs windstone gate 4, at the position of track inclined shaft 2 correspondence digging track crossdrift 5 and track gallery 6, digs haulage cross-cut 7 in the position of transport inclined shaft 3 correspondence in the position of return air inclined shaft 1 correspondence; Air door 8 is arranged on track gallery 6, air intake and return air can be made mutually not to mix, prevent Air escape branch;
B: open up two footrills from border, field with "nine squares": service shaft haulage tunnel 12 and service shaft return air footrill 16, then excavates and auxiliary cuts eye 14, a part cuts eye 13, service shaft gas lane 15, forms ventilation circuit and transportation system;
C: now service shaft haulage tunnel 12 tunnels base plate gas lane 9 by service shaft gas lane 15; Simultaneously tunnel base plate gas lane 9 from track inclined shaft 2 through track gallery 6, namely to tunnel 9 to base plate gas lane 9, base plate gas lane through simultaneously at two ends, shortens the gas tunnelling time greatly; Through rear base plate gas lane 9 forms loop, gas drainage under suction tunnel with service shaft haulage tunnel 12, need not excavate loop, gas drainage under suction lane again; Now directly extract out from service shaft haulage tunnel 12, this can reduce the engineering quantity of about half, draws out methane in advance to coal seam 18; Greatly shorten loop, reduce flowing resistance; Driving face haulage way 10 and work plane track gallery 19 form coal-face, just can working seam 18 to stopping adopting the coal between line 11, realize safety goes into operation in advance;
D: excavate next by service shaft gas lane 15 and adopt gas lane, face 17, prepares for next face of adopting draws out methane in advance, realizes mine safety and produce in advance.
