The utility model aims at providing a static pressure water injection hole sealing structure rational in infrastructure and with low costs, coal seam pressure relief vent that this structure can high -efficient shutoff ore deposit stress concentration.
Description
Technical field
This utility model is specifically related to a kind of static pressure water filling hole sealing structure.
Background technology
I am a diameter of 76mm of the beaten pressure relief vent in ore deposit stress concentration coal seam, is using pressure relief vent water filling, employs diameter 76mm
Hole packer carry out coal-bed flooding, but because the hole packer price of diameter 76mm is high, cannot be taken out by compression swelling during water filling, and such as
, for a long time all using the hole packer of diameter 76mm, cost input is big for fruit；But the hole packer according to diameter 42mm carries out water filling, hole
Mouth cannot block again.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure and low cost static pressure water filling hole sealing structure, this structure energy
Enough coal seam pressure relief holes efficiently blocking ore deposit stress concentration.
In order to achieve the above object, this utility model has a following technical scheme:
A kind of static pressure water filling hole sealing structure of the present utility model, ore deposit stress concentration coal seam drilling pressure relief vent, described release in the hole
Insertion water injection pipe；
Hole sealing bag, at the lateral symmetry 0.5m～0.7m being tied to described water injection pipe；
First cotton yarn back-up ring, described first cotton yarn back-up ring is between described hole sealing bag and water injection pipe inserting end.
Further, some hole sealing bags are also included, described hole sealing bag is 0.5m～1.0m with the spacing of hole sealing bag.
Further, described hole sealing bag is tied on water injection pipe by transparent rubberized fabric or cotton.
Further, the hole depth 12～15m of described pressure relief vent.
Further, described water injection pipe is steel whip sebific duct.
Further, after sealing of hole, described water injection pipe is wound around the second cotton yarn back-up ring, described first cotton yarn back-up ring and the second cotton yarn
Form sealing of hole area between back-up ring.
Due to taking above technical scheme, the utility model has the advantage of:
1. this utility model embodiment provides a kind of static pressure water filling hole sealing structure, ore deposit stress concentration coal seam drilling pressure relief vent,
Described pressure relief vent is inserted into water injection pipe；Hole sealing bag, at the lateral symmetry 0.5m～0.7m being tied to described water injection pipe；First cotton yarn gear
Circle, described first cotton yarn back-up ring is between described hole sealing bag and water injection pipe inserting end.Said structure can low cost solution
The problem of sealing of hole.

Specific embodiment
Hereinafter implement for this utility model is described, but be not limited to scope of the present utility model.
As shown in Figure 1-2, a kind of static pressure water filling hole sealing structure of the present utility model, ore deposit stress concentration coal seam drilling pressure relief vent 4,
Pressure relief vent 4 is inserted into water injection pipe 3, and specifically, the water injection pipe of the present embodiment is steel whip sebific duct；Hole sealing bag 5, lateral symmetry is tied to note
At the 0.5m～0.7m of water pipe 3, hole sealing bag 5 is tied on water injection pipe 3 by transparent rubberized fabric or cotton；First cotton yarn back-up ring 11 located at
Between hole sealing bag 5 and water injection pipe 3 inserting end.
It should be noted that according to actual needs can also by sealing of hole lengthening distance, after increase some hole sealing bags, sealing of hole
Bag is 0.5m～1.0m with the spacing of hole sealing bag.If the hole depth 12～15m of pressure relief vent, general hole sealing bag needs 3～5.
Further, after sealing of hole, water injection pipe is wound around the second cotton yarn back-up ring 12, the first cotton yarn back-up ring 11 and the second cotton yarn back-up ring
Form sealing of hole area 2 between 12.
Concrete static pressure water injecting pipeline arrangement environment is as follows:
Main line: be connected with big lane 4 water pipe from the big lane of crossdrift to water filled tunnel.Secondary pipeline: water filled tunnel two helps each cloth
Put 2 iron pipes, every 5-6m installs a pipe valve, 2 water pipes are connected with 4 water pipes.Water injection pipe: rubber hose braided with steel wire, length 5-
9m, thickness does not limit, and is connected with 2 pipeline pipe valves.
Concrete static pressure water filling sealing of hole operational approach is as follows:
(1) cleaning bottom of hole:
A even steps on hole phenomenon due to remaining more cinder in boring sometimes, therefore must use high pressure before use
Airduct or sweep a device float coal at rib 2m 3m blows off by the hole, to ensure that sealing of hole effect and water injection pipe can smoothly send into hole
Interior.
Airduct is connected by b with sweeping a device, and in addition to sweeping a work, remaining people withdraws to safety place.Then sweep a work to wear
Sweep eye with high-pressure blast after protective eye lens, remove coal (rock) powder in borehole.
After c has swept whole eyes, pressure wind sebific duct disk is put neatly.
(2) tie up bag: hole sealing bag is tied up on water injection pipe with transparent rubberized fabric or cotton yarn by claimed below；First group uses 2
Bag, lateral symmetry be tied at water injection pipe 0.5m, and front should suitably be wound around cotton yarn and stop that feed liquid flows into into water injection pipe；As
When needing sealing of hole lengthening distance, after increase hole sealing bag, spacing carries out tying up twining by 0.5m 1.0m.
(3) rub: tie up after the completion of twining, start to take out the divider on lower hole sealing bag successively, the suitable strength of both hands is not along
Equidirectional rub 20 seconds about, so that material is sufficiently mixed it should be noted that the time of rubbing of all of hole sealing bag can not be more than
1 minute.
(4) send water injection pipe: rub and carry out with sending water injection pipe simultaneously, after the completion of rubbing, another operator should be rapidly by water filling
Pipe is sent in boring, flows into solidification sealing boring between hole wall after hole sealing bag distending.
(5) seal: water injection pipe after having sent rapid cotton yarn, cotton be wound a back-up ring or with coal cinder, timber wedge etc.
Sealed.Can access purified water about after half an hour and carry out water filling.
It should be noted that the optional preferentially happy envelope of hole sealing bag in aforesaid operations；Rub hole sealing bag with handss quickly to rub as far as possible
Rub with the hands so as to be sufficiently mixed；Operator must wear glove and rub hole sealing bag.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate this utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.Here all of embodiment cannot be exhaustive.
Every belong to the obvious change that the technical solution of the utility model extended out or change still in of the present utility model
The row of protection domain.
