Description
Technical field
The utility model is related to the combination plugging device that a kind of coal mine gas drainage is used, and belongs to field of mine safety.
Background technology
Gas drainage under suction is to prevent one of effective measures of coal and gas prominent, and gas hole sealing device is to determine gas drainage under suction
The important step of effect.
At present, pit mining depth is increased sharply, and crustal stress is increased therewith.The gas hole sealing device master that colliery is generally used
There are polyurethane sealing aperture apparatus or cement mortar hole sealing device.In the actual production process of colliery, gas drainage hole sealing device makes
It is generally with the time 2-6 months, the time is relatively long.Creep can be occurred under larger crustal stress effect by drilling, and therefore, this two
Gas hole sealing device is planted there is also some problems, is mainly shown as：(1) for polyurethane sealing aperture apparatus, polyurethane material intensity
It is low, as drilling is by compression, it is impossible to stop the formation of leakage path, cause closure to fail, polyurethane price is higher in addition；
(2) the features such as compression strength of cement mortar is higher, but cement mortar has self-constriction, residing subsurface environment is poor, meeting
Cement shrinkage is caused to ftracture, so as to cause closure to fail.In addition, cement mortar setting time is longer.
The content of the invention
The purpose of this utility model is：A kind of gas pumping combination plugging device is provided, to solve existing plugging device
It is easy to closure failure, the problem of there is very big potential safety hazard.
To solve the above problems, intending combining plugging device, including drainage tube, combination section A using such a gas pumping
With combination section B, combination section A and combination section have been sequentially filled from gas aggregate site to the outside in gas pumping hole in gas pumping hole
B, one end of drainage tube sequentially passes through combination section B and combination section A by the outside in gas pumping hole and extends gas aggregate site, group
Conjunction portion A is entwined by polyurethane, towelling and iron wire, and iron wire is wound in tubular construction, filling polyurethane in tubular construction,
Towelling is wound on the outside of tubular construction, and combination section B is mixed by flyash, slag and gypsum, the outside in gas pumping hole
It is additionally provided with the Grouting Pipe extended in the B of combination section, Grouting Pipe and is additionally provided with ball valve.
In foregoing plugging device, in the B of combination section, by weight, cement, flyash, the mixed proportion of slag and gypsum are
1:0.3:0.15:0.1, combination section A and combination section B two ends are provided with baffle plate；
In foregoing plugging device, also include the slurry pipe that overflows, the one end for the slurry pipe that overflows extends the upside in the B of combination section, the other end
Lead to the outside in gas pumping hole；
In foregoing plugging device, combination section A is described towards cylinder stopper is additionally provided with the outside of one end of gas aggregate site
One end of drainage tube sequentially passes through combination section B, combination section A and cylinder stopper and extended at gas aggregate site, and drainage tube should
Gas port is provided with end.
Compared with prior art, the utility model can be answered with greatly bearing while plugging effect is ensured
The slow deformation that power is produced, and simple in construction, low cost.Polyurethane in the A of combination section can produce substantial amounts of foaming structure, due to
The guide effect of the towelling of iron wire winding, foaming structure is distributed in the circular space centered on drilling, while producing footpath
To stress；The cylinder stopper and baffle plate at two ends possess certain resistance, promote foaming structure preferably to infiltrate through around drilling
In the crack of generation.Combination section B can close the crack around drilling, simultaneously as combination section B early strong resistance to compression effect, can be with
Resist deformation faster at drilling initial stage and later stage larger crustal stress；Commonly it is easy to get additionally, due to material, flyash and slag exist
Mining area generally existing, cost can be reduced relative to simple use cement mortar.
