End connects static pressure water pipe by water injection pipe, and solid hole screen casing is arranged between taper guide shoe and the borehole wall of interface channel.Pass through this
Utility model greatly reduces single hole water filling cost；And water injection time, water filling distance, water injection rate etc. are substantially improved, and improve
Flood effectiveness.
Detailed description of the invention
Fig. 1 is a kind of structure connection diagram of coal seam water infusion device provided by the utility model.
Specific embodiment
Many details are explained in the following description in order to fully understand the utility model.But this is practical new
Type can be implemented with being much different from other way described herein, and those skilled in the art can be practical new without prejudice to this
Similar popularization is done in the case where type intension, therefore the utility model is not limited by following public specific implementation.
Secondly, the utility model is described in detail using schematic diagram, when the utility model embodiment is described in detail, for convenient for
Illustrate, schematic diagram is example, should not limit the range of the utility model protection herein.
Refering to fig. 1, Fig. 1 is a kind of structure connection diagram of coal seam water infusion device provided by the utility model.A kind of coal
Layer water filling device, using coal seam km drilling to coal seam carry out water filling include: static pressure water pipe 1, water injection pipe 2, solid hole screen casing 7,
Borehole wall 9 and taper guide shoe 10；Wherein, the interface channel for being connected to km drilling is drilled through on working face of coal seam, passes through cone
Outside 10 one end of shape guide shoe connection working face of coal seam and interface channel is drilled through, the other end connects static pressure water pipe 1 by water injection pipe 2,
Solid hole screen casing 7 is set between taper guide shoe 10 and the borehole wall 9 of interface channel.
Wherein, the position setting hole sealing tube 6 that interface channel mouth is contacted with taper guide shoe 10 is to protect the taper guide shoe
10, hole sealing tube 6 coats the taper guide shoe 10 for being set to interface channel mouth.
Wherein, water injection pipe 2 is connected in the side wall of the taper guide shoe 10 on the outside of interface channel, and taper guide shoe 10 is located at
It is closed by valve 5 one end on the outside of working face of coal seam.
Wherein, a valve 3 is set on water injection pipe 2, to control the water flow in water injection pipe 2.
Wherein, flowmeter 4 is set on water injection pipe 2, is monitored with the quantitative water flow in water injection pipe 2.
On the basis of original " hole is dual-purpose " water-filling method, innovation carries out coal-bed flooding using km drilling, passes through
For a long time, it fills the water at a distance, increases coal body moisture, moisten coal body, and reduce the intensity and brittleness of coal, increase plasticity,
The Dust Capacity that various processes generate when mining fundamentally is reduced, while reducing water filling cost, belongs to Mine Dust and administers scope.
Existing water injection time is short, water injection rate is few, flood effectiveness is poor, single hole when mainly solving stope using common pouring water into borehole
Fill the water the problems such as at high cost.
The technical solution adopted in the utility model is: km drilling construction distance is utilized, generally in 300-500m, and
