Design of early-warning system of gas outburst based on dynamic characteristics of pressure monitoring

According to occurrence of coal and gas outburst and technology of related dynamic safety information collection on coal face, the paper designed an early-warning system of gas outburst on coal face based on dynamic characteristics of pressure monitoring. The system can dynamically extract real-time data from massive pressure monitoring data, and finally realizes intelligent analysis and real-time early-warning of coal and gas outburst on coal face, and it also has efficient data management capabilities. The system has achieved good effects in the field test.
