Background technology
Hole pumping and mining gas has become a kind of main method of coal mine gas release release, for the coal seam that occurrence condition is complex, such as weak seam, its gas pumping hole easily caves in closure, gas drainage system is difficult in maintenance, the method collapsed in current preventing and treating coal bed gas extraction hole mainly uses guard aperture sleeve pipe and macrovoid packing material to fill drainage holes, but current working site still the most effective fixed point guard aperture method and apparatus, universal guard aperture sleeve pipe is the most with high costs, operating time is long, waste time and energy, efficiency is low, guard aperture redundancy, and be difficult to carry out in the gas pumping hole of remote long drilled holes, cause gas pumping hole utilization rate low, extracting result is undesirable.
Summary of the invention
For defect present in above technology; this utility model provides a kind of mash gas pumping drilling fixed point aperture guard device; this device can protect the position that easily caves in such as mash gas pumping drilling coal seam section or soft section of rock stratum exactly; especially high inclination-angle boring; improve hole pumping and mining gas effect; utilize this device can quickly, effectively and precisely protect gas pumping hole, save material simultaneously, reduce workload and time.
This utility model includes, porous casing 1, capsule 3, the pipe collar 2 of porous casing 1 is connected on capsule 3, capsule air inlet pipe 4, connects the conduit 6 of capsule air inlet pipe 4, connects the three-way valve 7 of capsule air inlet pipe 5 and conduit 6, the check valve 5 being arranged on conduit 6, is attached to the bonding jumper 7 being covered with burr 9 of capsule 3 outer surface.
Preferably, described many borehole jacks 1 pipe is higher for intensity, stability preferable irony sleeve pipe; can support to gas pumping terminate, its surface is covered with mesh, it is simple to gas passes; the length of porous casing determines according to required protection drillable length, and diameter determines according to bore diameter.
Preferably, described bonding jumper 7 outer surface is covered with nail shape burr 9, and burr has stronger grasp force, and utilizes a-cyanoacrylate class glue by bonding jumper 7 inner surface gluing at capsule 3 outer surface.
Preferably, described capsule 3 is ring-type, a length of 500mm, internal ring is nested with the pvp pipe of diameter 45mm, non-gas injection state external diameter is 70mm, gas injection pressure≤4MPa, and after gas injection, the effective expansion rate of volume is 60-80%, after gas injection, capsule volume is more than boring aperture, it can be ensured that the burr 9 on bonding jumper 7 outer surface can closely capture drill hole inner wall.
Preferably, described conduit being provided with one-way cock 5, in can ensureing capsule 3, gas will not leak after gas injection terminates.
The scheme of above-mentioned offer is provided, porous casing is pushed to coal seam section or soft rock section etc. in gas pumping hole and needs guard aperture position, utilize underground pressure air system that compressed air is injected the capsule 3 at porous casing two ends, capsule 3 expands and fits tightly drill hole inner wall, there is certain frictional force, the bonding jumper 7 of capsule 3 outer surface carries jagged 9 simultaneously, burr 9 captures drill hole inner wall under the inflatable elastomeric stress effect of capsule, further increase frictional force, under the fixing effect of front and back's capsule 3, porous casing 1 is fixed on appointment position, make it that relative slip of position not occurred by coal petrography slag particle and self gravitation effect, in guaranteeing boring, soft wall is effectively protected, until terminating to gas pumping.
Compared with prior art, this utility model achieves to pinpoint protects the weak hole wall section of boring, the advantages such as while ensureing guard aperture quality, cost-effective, the guard aperture cycle is long, reduction labor intensity, shortening guard aperture processing operation time, safe and reliable.

Wherein in figure: 1 porous casing, 2 pipe collars, 3 capsules, 4 capsule air inlet pipe, 5 check valves, 6 conduits, 7 bonding jumpers, 8 three-way valve, 9 burrs, 10 spiral interfaces, 11 rock stratum, 12 coal seams.
Detailed description of the invention
In order to be illustrated more clearly that the present invention, below in conjunction with case study on implementation and accompanying drawing the present invention done further description:
As shown in Figure 1, a kind of mash gas pumping drilling fixed point aperture guard device includes, porous casing 1, the capsule 3 of porous casing 1 is connected by pipe collar 2, connect the capsule air inlet pipe 4 of capsule 3, connected the conduit 6 of capsule air inlet pipe 4 by three-way valve 8, the check valve 5 being arranged on conduit 6, is attached to the bonding jumper 7 being covered with burr 9 of outer surface.
nullAs shown in Figure 3，Porous casing 1 is pushed to coal seam section or soft rock section etc. in gas pumping hole and needs guard aperture position，Utilize underground pressure air system that compressed air is injected the capsule 3 of porous casing 1 front end by capsule air inlet pipe 4，And by injecting the capsule 3 of porous casing 1 end with three-way valve 8 in capsule air inlet pipe 4 and conduit 6，Capsule 3 volumetric expansion fits tightly drill hole inner wall，There is certain frictional force，The bonding jumper 7 of capsule 3 outer surface carries jagged 9 simultaneously，Burr 9 captures drill hole inner wall under the inflatable elastomeric stress effect of capsule 3，Further increase frictional force，Under the fixing effect of front and back's capsule 3，Porous casing 1 is fixed on appointment position，Make it that relative slip of position not occurred by coal petrography slag particle and self gravitation effect，After gas injection terminates，Gas injection equipment is exited by spiral interface 10 spiral，In check valve 5 has ensured capsule 3 under differential pressure action effectively, gas does not leaks，Thus ensure that the air-tightness that capsule 3 blocks.In using the method to make boring, soft wall is effectively protected, until to gas pumping end-of-job.
Compared with prior art, this utility model achieves to pinpoint protects the weak hole wall section of boring, the advantages such as while ensureing guard aperture quality, cost-effective, the guard aperture cycle is long, reduction labor intensity, shortening guard aperture processing operation time, safe and reliable.
