为了解决汪家寨煤矿煤与瓦斯突出预测难题,应用煤与瓦斯突出实时跟踪预警系统,分析了P41104掘进工作面过断层、煤柱区、保护层范围期间同一时空上微震信号(大事件、小事件、能量)与瓦斯参数的相互变化趋势,得出了突出危险性等级。根据预警结果采用相应的防突措施和掘进工艺,大大提高了矿井的安全和生产效益。 In order to solve the coal and gas outburst prediction problem in Wangjiazhai coal mine, the application of coal and gas outburst real-time tracking and early warning system was used to analyze the microseismic signals of the same time and space in P41104 heading face crossing the fault, coal pillar area and protective layer Events, energy) and gas parameters of the trend of mutual change, reached the prominent risk level. According to the early warning results using the corresponding anti-sudden measures and driving technology, greatly improving the mine safety and production efficiency.
