Description
Technical field
The utility model belongs to collery's surface movement prevention and treatment and field of measuring technique, is related to a kind of thin suitable for underground coal mine
Application technology during discharging water, the spy discharge method and device of specially a kind of coal mine overlying rock water.
Background technique
During coal production, it is mined out above to cover coal seam, forms large area goaf, at back production the following group coal seam, for
On cover old dead zone ponding in coal seam and the rock stratum water in each water-bearing layer carries out unrestrained and pressure release.Usually near drilling sites
Water storage is excavated, the water in drilling is discharged into sump by installation drainage equipment, then drains into mining area sump or central water by water pump
Storehouse needs to set special messenger and drains, and needs to consume the energy in drainage procedure, time-consuming and laborious, and the opportunity drained is not easy to control.
Utility model content
The purpose of this utility model is artificial present in the draining pressure leak process of current coal mine gob to solve
The problem of large labor intensity, drainage works low efficiency, and a kind of tapping equipment of coal mine overlying rock water is provided.The utility model
It is achieved by the following technical solution.
A kind of tapping equipment of coal mine overlying rock water, including the casing being arranged in roof, the casing
The outside of roof is arranged in collar extension, and the collar extension of described sleeve pipe is connected by the high pressure flange disk welded with threeway, described
Threeway be connected separately with drainpipe and control gate valve, flowmeter, the collar extension of the casing are provided on the drainpipe
On be additionally provided with pressure gauge, the drainpipe is connected with mining area sump.
Further, the drainpipe is hose or seamless steel pipe.
The utility model is generated compared with the existing technology to be had the beneficial effect that.
The present apparatus increases pressure gauge, flowmeter by connecting drainpipe outside casing, is acted on using the pressure of upper water
Water in drilling can be importing directly into discharge pipe line and drain into mining area sump.Pressure gauge is installed in orifice sleeve, is measured
Casing nozzle is connect with discharge pipe line, is covered by using the pressure of casing nozzle water when pressure is higher than discharge pipe line by pressure
The water of rock stratum and old dead zone is immediately discharged to mining area sump or wellhole.Big water of constructing at the scene is eliminated using the present apparatus
Storehouse, it is only necessary to 1, interim water nest of constructing, drainage works when for drilling；The equipment such as installation water pump, switch are eliminated simultaneously；It is slow
The consumption of labor intensity and the energy is solved.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1 is casing, and 2 be threeway, and 3 be drainpipe, and 4 be pressure gauge, and 5 be flowmeter, and 6 be control gate valve, and 7 be to adopt
Area's sump, 8 be above to cover limestone aquifer.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, tie
Embodiment and attached drawing are closed, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein
It is only used to explain the utility model, is not used to limit the utility model.This is described in detail below with reference to examples and drawings
The technical solution of utility model, but the scope of protection is not limited by this.
As shown in Figure 1, a kind of tapping equipment of coal mine overlying rock water, including the casing 1 being arranged in roof, set
The outside of roof is arranged in the collar extension of pipe 1, and the collar extension of casing 1 is connected by the high pressure flange disk of welding with threeway 2, institute
The threeway 2 stated is connected separately with drainpipe 3 and control gate valve 6, and flowmeter 5 is provided on drainpipe 3, is gone back on the collar extension of casing 1
It is provided with pressure gauge 4, drainpipe 3 is connected with mining area sump 7.Drainpipe 3 is three cun of hoses or 108 seamless steel pipes.
It when placing casing 1 in top plate, is designed according to leting speeper, limestone aquifer 8 or old empty water is covered in prediction
Water, hydraulic pressure design the length of orifice sleeve to be mounted, aperture length 10m, and aperture uses φ 113mm coring bit aperture,
Then tripping in φ 108mm casing 1 carries out hole-sealing grouting using grouting pump using the double slurries of cement-sodium silicate, and grouting pressure is
It is expected that 2-2.5 times of hydraulic pressure, laggard pressure testing of passing through to be solidified, change after design pressure to be achieved φ 65mm or 75mm drill bit creep into
Whole hole.1 collar extension of casing welds high pressure flange disk, is connected with the threeway for being equipped with drainpipe 3 and control gate valve 6, and in casing 1
Collar extension connects pressure gauge 4, and flowmeter 5 is connected on drainpipe 3.Pressure is measured, when pressure is higher than discharge pipe line, will be covered, 1 pipe
Mouth is connect with 3 tunnel of drainpipe, and the water of overlying rock and old dead zone is immediately discharged to exploiting field water using the pressure of 1 nozzle water of casing
Storehouse 7 or wellhole.
The above content is the further descriptions done in conjunction with specific preferred embodiment to the utility model, cannot
Assert that specific embodiment of the present utility model is only limitted to this, for the utility model person of an ordinary skill in the technical field
For, under the premise of not departing from the utility model, several simple deduction or replace can also be made, all shall be regarded as belonging to
The utility model determines scope of patent protection by the claims submitted.
