| titleOfInvention | Utilize the system of search gas test coal body permeability |
| abstract | Using the system of search gas test coal body permeability, belong to technical field of mine safety, to overcome prior art really to react deep coal body under reset condition the shortcomings that Penetration Signature.Include antipriming pipe, communicating pipe and the three-way pipe being sequentially connected including gas injection, gas injection observation and infiltration observation pipeline, gas injection pipeline, the three-way pipe is indirectly connected with storing the gas cylinder of search gas；Gas injection observation pipeline includes antipriming pipe, communicating pipe and the first concentration detector being sequentially connected；Infiltration observation pipeline includes antipriming pipe, communicating pipe and the three-way pipe being sequentially connected, and the other both ends of the second three-way pipe are connected to pressure gauge and the second concentration detector；First concentration detector is connected with main frame respectively with the second concentration detector；Search gas is injected by gas injection pipeline, gas content in the hole where the antipriming pipe of gas injection pipeline observed using gas injection observation pipeline, and utilizes the gas of infiltration observation pipeline observation infiltration；The gas permeability suitable for test coal body. |
