Coal and gas outburst mines and gas mine ground fixed extraction from the gas system must be established, at the same time with coal seam gas drainage and extraction methods of mine goaf, according to the need, high and low negative pressure extraction gas systems were established. In order to strengthen the gas extraction monitoring, gas drainage gas extraction from mining wells was equipped with monitoring system, real-time monitoring network parameters and equipment of the stop state, etc. Through the monitoring system, a glance for the extraction of the parameters for testing was clear, effective means were taken to control smoke volume, Separate source extraction and monitoring were realized in the true sense.
