Further, floral tube is provided with some presbyopia, and presbyopia spacing is 3 centimetres, and floral tube total length is more than or equal to 4 meters.
Further, the caliber of real pipe and floral tube is 1 cun.
Further, a diameter of the 2 of tail pipe1/2Very little.
Further, a diameter of 1/2 cun of pipe collar.
Further, adapter is 1 cun turn 21/2Very little adapter.
Further, pipe collar connects Pressure gauge.
Further, ferrum baffle plate and two ends thereof are enclosed with cotton yarn；Floral tube and the real pipe of part are positioned in boring to be measured；Cotton yarn bag
Wrap up in the thickness of the inclusion enclave that ferrum baffle plate is formed more than bore diameter；Inclusion enclave is provided with sealing material condensation formation between hell
Sealing of hole body.
Compared with prior art, the beneficial effects of the utility model are:
In the country rock gas exploration boring occur Abnormal Methane Emission, directly carry out the mensuration of country rock atmospheric pressure, the most individually construct
Country rock atmospheric pressure measures boring.All of exploration boring is used unified hole sealing technology, on-the-spot according to country rock in exploration boring
Gas situation of gushing out carries out the real time measure of country rock atmospheric pressure, it is achieved country rock gas and pressure thereof with visiting with survey.During shorter test
Between the most do not affect follow-up exploration boring construction, do not affect drilling operation and work surface normally tunnel.For kerosene oil-gas mineral intergrowth
Well seat earth country rock atmospheric pressure measures and provides an effective technological approaches.

Detailed description of the invention
As it is shown in figure 1, this utility model one mine country rock gas pressure measurement drainage device, including ball valve 5, Pressure gauge 7, pipe collar
6, real pipe 1, floral tube 2, ferrum baffle plate 8 and cotton yarn 11.
The lower end of real pipe 1 connects floral tube 2, and the upper end of real pipe 1 is provided with ball valve 5；Real pipe 1 top is by adapter even
Connect the diameter tail pipe 4 more than real pipe 1.Distance real pipe 1 top 15, the lower end centimeters welding pipe collar 6 of ball valve 5 is used for connecting pressure
Table 7；Real pipe 1 is welded with ferrum baffle plate 8 with the junction of floral tube 2.Under fashionable, wrap up ferrum baffle plate 8 and two ends thereof with cotton yarn 11, parcel
The thickness of body is more than bore diameter.
Floral tube 2 is to process presbyopia on real pipe 1 perisporium, and presbyopia spacing is 3 centimetres, and floral tube 2 total length is not less than 4 meters.
The caliber of real pipe 1 and floral tube 2 is 1 cun；Real pipe 1 and floral tube 2 are 2 meters every, and real pipe 1 total length seals according to reality
Hole length determines.
A diameter of the 2 of tail pipe 41/2Very little；
A diameter of 1/2 cun of pipe collar 6.
Adapter is 1 cun and turns 21/2Very little adapter.
The operational approach of this utility model a kind of mine country rock gas pressure measurement drainage device, specifically includes following steps:
The first step: construction pressure measurement-extraction borehole；
Second step: by wrapping to enter in boring under the mine country rock gas pressure measurement drainage device of cotton yarn 11, make Pressure gauge 7, ball valve 5
It is exposed to boring outside；
3rd step: inject rapid hardening sealing material in hell by Grouting Pipe 3 and carry out sealing of hole；
4th step: when substantially gushing out without country rock gas in exploration hole, does not carry out country rock atmospheric pressure mensuration work, by pipe collar 6
Closure, makes ball valve 5 be in open mode, i.e. achieves the extraction of exploration boring.When country rock gas Abnormal Methane Emission occurs in exploration hole
Time, close other extraction boreholes, and stop the construction that follow-up exploration is holed, after whole device connects and sealing of hole Hou Ning completes,
Close ball valve 5, country rock atmospheric pressure mensuration can be carried out by Pressure gauge 7, after the test of country rock atmospheric pressure terminates, open ball valve 5, i.e.
