Embodiment 1
Present embodiments provide a kind of coal seam flooding hole sealing device, including sealing of hole portion 1, waterflood path 2 with suppress passage 3, by described waterflood path 2 to coal-bed flooding；Described sealing of hole portion 1 ring set is sealingly disposed in the periphery of described waterflood path 2, and described sealing of hole portion 1 is collapsible or the boring in coal seam is blocked by expansion；Described passage 3 of suppressing connects with described sealing of hole portion 1, and water can be suppressed feeding sealing of hole portion 1.
When needing, by the boring 26 in coal seam 7, coal seam 7 is carried out water filling, hole packer is put into boring 26, pressuring pump 4 is utilized to connect with described passage 3 of suppressing, pressuring pump 4 is utilized to be weighed into water by suppressing passage 3 to its sealing of hole portion 1 connected, sealing of hole portion 1 is constantly expanded, 26 sealing blockings until sealing of hole portion 1 will hole.Sealing of hole portion 1 ring set is sealingly disposed in the periphery of described waterflood path 2 it should be understood that for being tightly connected between sealing of hole portion 1 and waterflood path 2, sealing of hole portion 1 itself is also to seal.Again by waterflood path 2 to coal-bed flooding, after water filling terminates, it is not necessary to during sealing of hole so that the pressure in sealing of hole portion 1 releases, sealing of hole portion 1 recovers to shrink initial condition, is taken out by boring 26, reuses next time.Sealing of hole portion 1 is inflatable to be blocked boring 26, it is not necessary to cement mortar 5 solidifies water injection pipe 6 sealing of hole, and labor intensity is less, and sealing of hole speed is fast, and sealing of hole portion 1 can be made after water filling terminates to shrink, and whole hole packer takes out recycling, cost-effective, repeatable utilization.Because being provided with waterflood path 2 and suppressing passage 3 channel structure, can by suppress passage 3 sealing of hole portion 1 is suppressed expansion boring is blocked after, by waterflood path 2 water filling, not interfering with the sealing of hole effect in sealing of hole portion 1 while water filling, sealing of hole state can persistently keep.
The present embodiment is preferred, and described waterflood path 2 is provided with one way stop peturn valve 13 away from described one end suppressing passage.Guarantee when the complete outer water source of water filling stops, it is to avoid water injection rate is revealed by water filling port, it is ensured that flood effectiveness.
The present embodiment is preferred, and the other end of described waterflood path is provided with water filling port.So arrange and facilitate waterflood path to connect with outer water source, facilitate water filling.
Described herein, during traditional waterflood, it is provided with anti-anti-backflow device at the outlet 8 of water injection pipe 6, as shown in Figure 2；Traditional anti-anti-backflow device includes locking pressure ball 9 and controlling spring 10, described control spring 10 one end is connected on outlet 8 inwall, the other end controlling spring 10 is connected on described lock pressure ball 9, and described lock pressure ball 9 cooperates can block described filling pipe 12 with the block mouth 11 of setting on described filling pipe inwall.During by water injection pipe 6 water filling, lock pressure ball 9 can be impacted by hydraulic pressure, controls spring 10 and is compressed, and lock pressure ball 9 no longer matches with block mouth 11, and current flow out from outlet 8, are also prevented from current opposite direction Liu and enter filling pipe.This design is affected relatively big by water injection pressure, and when on-the-spot water filling is forced down, lock pressure ball can not normally be opened, and water filling work cannot be normally carried out；Discharge is also had certain requirement；In hole, the water yield for immersion coal seam can easily produce refluence, flows out boring, and when intermittent water injection work, the water yield can flow out boring repeatedly, causes flood effectiveness low, is even unable to reach predetermined flood effectiveness.
The present embodiment is preferred, described in suppress passage 3 and be provided with from locked pressure mouth 14 away from one end, described sealing of hole portion 1, described from locked pressure mouth 14 can to described suppress passage 3 and described in suppress the sealing of hole portion 1 of passage 3 connection and carry out pressure closure and stablize hydraulic pressure.
It is weighed into water to its sealing of hole portion 1 connected so that sealing of hole portion 1 constantly expands, until after borehole sealing is blocked by sealing of hole portion 1, being provided with from locked pressure mouth 14, sealing of hole portion 1 can being carried out pressure closure from locked pressure mouth 14 by suppressing passage 3；Waterflood path 2 is two different passages from suppressing passage 3 simultaneously, it is independent of each other, one way stop peturn valve 13 and being independent of each other between locked pressure mouth 14, change above-mentioned conventional art is affected bigger defect by water injection pressure, sealing of hole pressure and sealing of hole time can be operated by operator as required, sealing of hole pressure and sealing of hole time are controlled, it is ensured that sealing of hole effect；From the self-locking laminated structure of locked pressure mouth 14, operator is facilitated to operate；Protect sealing of hole pressure from locked pressure mouth 14 not reveal, can sealing of hole for a long time, it is ensured that flood effectiveness.More do not have refluence to portal, affect the phenomenon of plugging effect.
The present embodiment is preferred, described includes sealing pressure passageway 15, water pressure inlet 16, locking member and hydraulic pressure outlet 17 from locked pressure mouth 14；
