Application of outburst warning technology based on gas emission characteristics in Xiayukou Coal Mine

Early warning of coal and gas outburst based on gas emission characteristics is a more feasible and effective outburst prediction method. In order to make up for the limitations of the existing traditional contact coal and gas outburst prediction methods, the gas emission dynamic characteristics were used to carry out coal and gas outburst warnings, and the Xiayukou Coal Mine outburst warning system based on gas emission characteristics was constructed. The field application practice shows that the system can evaluate and warn the dangerous state and development trend of the working face stably and reliably. The system has tracked and inspected the tunnel length in the underground mine over 500m, and caught many abnormal gas phenomena in advance, and realized the real-time monitoring, online analysis, and intelligent early warning of coal and gas. It has extremely important practical significance for improving mine gas control and daily safe and efficient production.
