Abstract
A kind of removing method of hole packer, belongs to colliery digging apparatus field, comprises the following steps：1st, water hole is got at 200 300 millimeters of water injection hole where hole packer in the hole packer side of delay, its apopore axial line and water injection hole axial line cocurrent and parallel, the depth of its apopore are more than 300 millimeters of hole packer front end depth；2nd, the water under high pressure on hole packer is started, to being trapped in water filling in the hole packer in coal seam；3rd, water filling is stopped；4th, hole packer is taken out；The hole packer in coal seam, the characteristics of reducing supplies consumption are trapped in the taking-up for being capable of simplicity.
Description
Technical field
The invention belongs to colliery digging apparatus field, more particularly to a kind of removing method of hole packer.
Background technology
Hole packer is needed during mining to a kind of instrument used during coal-bed flooding, and its two ends is metal material, in
Portion is a kind of hollow tubular thing of compounded rubber material, and there is small apopore its front end, and there is interface section rear end with high-pressure water pipe；
During work, hole packer is put into the hole being drilled on coal seam, its rear end is connected with high-pressure water pipe, start water under high pressure, water is just
Coal seam can be entered by the apopore of hole packer front end；Because hydraulic pressure is high, water causes the coal seam around hole packer to press into coal seam
Power produces change, adds hole packer diameter in 50 millimeters and length in 1300 millimeters, and the material of most of length
For composite rubber material, water under high pressure causes coal seam pressure increasing, the pipe deformation that compounded rubber material is made, and hole packer is just after water filling
Do not take not come out, be trapped in hole in hole, pullling can cause hole packer to be broken by force, waste substantial amounts of hole packer.
The content of the invention
The problem of being trapped in coal seam after being worked for existing hole packer, the present invention proposes a kind of taking-up side of hole packer
Method, it is characterised in that：Comprise the following steps：1st, in the hole packer side of delay apart from the water injection hole 200-300 where hole packer
Water hole is got at millimeter, its apopore axial line and water injection hole axial line cocurrent and parallel, the depth of its apopore are more than hole packer
300 millimeters of front end depth；2nd, the water under high pressure on hole packer is started, to being trapped in water filling in the hole packer in coal seam；3rd, note is stopped
Water；4th, hole packer is taken out；Described step 1 is that the hole of diameter same with former hole packer hole is got out on same coal seam, it is not necessary to
More exchange device convenient construction, it is two or more that it, which punches quantity,；Described step 2 is to implement original water-filling method again,
Noted water under high pressure punctures the coal seam between water injection hole and apopore, water flow and by between water injection hole and apopore from apopore
Washout fall；Described step 3 is that current are washed away in the coal seam between hole packer and lateral orifices by water completely after charging
Carried out after falling；Described step 4 is borehole enlargement after hole packer periphery coal seam is washed out by water, and hole packer is under loosening state
Carry out.
Beneficial effect
The beneficial effects of the present invention are the taking-up for being capable of simplicity is trapped in the hole packer in coal seam, reduces supplies consumption.
Brief description of the drawings
Fig. 1 is the principle schematic of the present invention
1. coal seam, 2. hole packers, 3. apopores.
Embodiment
In order to further illustrate technical scheme, the specific embodiment party of the present invention is further illustrated in conjunction with accompanying drawing
Formula, such as Fig. 1, when needing water filling on coal seam 1, get out water injection hole, hole packer 2 are fitted into be drilled water injection hole, in sealing of hole
The tail end of device 2, that is, expose the one end in coal seam 1, high-pressure water is connected, to the water filling of coal seam 1, due to the change of of hole packer 2 itself
The pressure change to hole packer 2 that shape and coal seam 1 are produced due to water filling, produces crimp, hole packer 2 is just to hole packer 2
It is compressed in the middle of coal seam 1, is not easily taken out；I.e. in 2 liang of 230 millimeters of lateral extent water injection hole centre distances of water injection hole hole packer
Place, horizontal direction is identical with water injection hole direction, gets out two diameters apopore 3 parallel with water injection hole identical, its apopore 3
Depth is more than 300 millimeters of the hole inner end present position of hole packer 2, or uses centered on water injection hole, in the milli of radius 230
3-4 apopore is got out on the circumference of rice；Unlatching water under high pressure, the water filling into hole packer 2, noting water under high pressure can be by water injection hole with going out
Coal seam 1 between water hole 3 punctures so that, water under high pressure flows out from inside to outside from apopore 3, because flow velocity is larger, can by water injection hole with
Coal seam 1 between apopore 3 is washed out, so as to reduce pressure of the coal seam 1 to hole packer 2, expands the space around hole packer；
After the coal of coal seam 1 between water injection hole and apopore 3 is washed away completely, stop water filling, now, easily just can be from water injection hole
Hole packer 2 is taken out, the implementation of the present invention is just completed.
Claims (1)
1. a kind of removing method of hole packer, it is characterised in that：Comprise the following steps：1st, in the hole packer side distance envelope of delay
Water hole is got at 200-300 millimeters of water injection hole where the device of hole, its apopore axial line and water injection hole axial line cocurrent and parallel, its
The depth of apopore is more than 300 millimeters of hole packer front end depth；2nd, the water under high pressure on hole packer is started, to being trapped in coal seam
Water filling in hole packer；3rd, water filling is stopped；4th, hole packer is taken out；Step 1 be got out on same coal seam with it is same with former hole packer hole
The hole of sample diameter, it is not necessary to more exchange device convenient construction, it is two or more that it, which punches quantity,；Step 2 is by original water-filling method
Again implement, note water under high pressure and puncture coal seam between water injection hole and apopore, water flowed out from apopore and by water injection hole with
Washout between apopore falls；Step 3 is that current are complete by water by the coal seam between hole packer and apopore after charging
Carried out after washing away；Step 4 is borehole enlargement after hole packer periphery coal seam is washed out by water, and hole packer is in enter under loosening state
OK.
