Outburst Hazard Prediction Based on the Monitoring Data in Heading Face

Abstract:

To analyse the outburst hazard of heading face in real time, based on the mechanism of coal and gas burst and its forecasting principle, four real-time predictive indicators were proposed, which involve three aspects: crustal stress, gas, physical and mechanical properties of coal, and had a verification test. The results show that the real-time predictive indicators are in good agreement with the traditional indicators, whose deviation are mainly caused by gas exceeded. With the monitoring data in monitoring system, the outburst hazard of heading face could be predicted in real time, which could help to prevent outburst.
