This releasing pipe, the aperture above macropore is Grouting Pipe, and the aperture below macropore is aerofluxus/slurry recovering tube；It is sequentially provided with on hole sealing tube
First slip casting check valve, explosive valve and the second slip casting check valve, hole sealing tube sequentially passes through first paragraph pouch and second segment pouch, the
One slip casting check valve and the second slip casting check valve are respectively provided at first paragraph pouch and the inside of second segment pouch.
Preferably, second segment pouch is away from extraction screen casing tail end 20-40cm.
Described first paragraph pouch and second segment pouch are respectively adopted double-layer filter cloth, and internal layer intensity is high, and drainability is good；Outer layer is
The filter cloth that wearability is good, elastic force is high.
Preferably, first paragraph pouch and second segment pouch are sequentially fixed at sealing of hole with band, iron wire and three layers of adhesive tape respectively
Guan Shang, improves sealing effectiveness.
Couple between described hole sealing tube and use spigot-and-socket or taper pipe thread formula.
The extension tube attached being connected with aerofluxus/slurry recovering tube it is additionally provided with, further aerofluxus or return slurry on described hole sealing tube.
After target site boring in coal seam, described mining hole packer is inserted in hole, then by Grouting Pipe inside
Portion's slip casting, prolongation over time, grouting pressure is increasing, when reaching certain pressure value, the first slip casting check valve and
Two slip casting closed check valves, explosive valve explosion, when aerofluxus/slurry recovering tube mouth of pipe has slurry to flow out, now stop slip casting, then profit
Gas extraction is started by the macropore in hole sealing tube i.e. gas drainage pipe under negative pressure with vacuum pump.
This utility model is had the beneficial effect that
The hole sealing tube being provided with in this utility model is the integrated pipe structure in interior tubular type three hole, macropore be used for gas drainage under suction, two
Individual aperture is used separately as Grouting Pipe and aerofluxus/slurry recovering tube, owing to using inner tube defeated slurry mode, can effectively reduce pouch external diameter, from
And reduce bore diameter, effectively reduce boring cost and sealing material takes, improve work efficiency, reduce labor intensity；Aerofluxus/return
Sealing of hole section air can effectively be discharged by slurry pipe design, can exhaust condition directly perceived and the most completely starching, it is to avoid because of cannot aerofluxus and affect
Sealing of hole effect, thus improve sealing of hole qualification rate and efficiency；The connected mode of tubing makes any group of sealing of hole position, sealed borehole length
Close；Sealing of hole pouch fixes factorial praluction, and simple assembling is only done at scene, simple to operate, easy to use, the most reliably.
