Lighter air drill and pneumatic pick is needed to complete, workload is smaller.
2nd, when probe hammers into coal body, by the extruding of coal body and probe, can be achieved after probe hammers into coal body certain distance
It is self-styled, ensure that the Real Gas pressure of its present position of probe pressure-measuring pipe can be measured.
When the 3rd, due to hammering into probe, gas can only be scattered and disappeared by probe endoporus, and loss amount is smaller, and needed for whole pressure measurement
Gas pressure balance space is smaller, so the required testing time is shorter.
4th, because supervisor employs hierarchical form, can increase in coal seam that may be bad using the self-styled effect of straight pipe type probe
Add self-styled effect, ensure the accuracy of gas pressure measurement.
5th, the utility model is not only able to shorten the gas pressure measurement cycle, improves the success rate of piezometry, moreover it is possible to
Measure probe follows closely process into coal body, can by follow closely into complexity judge the Failure type of coal, be gas relevant parameter
Measure provide foundation.
