Continuous flow method coal lane outburst prediction device as an important new technology in predicting coal roadway outburst hazard,whether or not it could work stably and reliably is related to the normal working face advance and the personal safety in the coal mine. While in the process of simulation experiment which use continuous flow method coal lane outburst prediction device to predict coal roadway heading face outburst risk, there is a problem that when borehole spraying happens,gas carrying large...
