摘要: 在分析了微震和地音监测技术各自优势的基础上,结合ARAMIS M/E微震监测系统与ARES-5/E地音监测系统在华丰煤矿的应用效果,提出了综合微震和地音监测技术的冲击地压防治方法。理论分析表明,微震监测技术配合地音监测技术,不仅在时间上对冲击危险起到了即时预测,而且在空间上对冲击危险起到了从局部预测到区域预测的分级预测效果,还可以实现煤岩体破裂过程中能量从集聚至释放整个过程的全程监测。实践表明,ARES-5/E地音监测系统能够对冲击事件的发生起到提前预测;应用微震和地音综合监测技术,能够结合2种技术的优势,在冲击地压的防治中取得效果。Abstract: Based on the analysis on the each advantages of the micro seismic and ground acoustic emission monitoring and measuring technologies, in combinatio n with the application effects of the ARAMIS M/E micro seismic monitoring and measuring system and the ARES-5/E ground acoustic emission monitoring and measurin g system to Huafeng Mine, the mine strata pressure bumping prevention and control method with the comprehensive micro seismic and ground acoustic emission monit oring and measuring technology was provided.The theoretical analysis showed that the micro seismic monitoring and measuring technology coordinated with the ground acoustic emission could not only in timely have a prompt prediction of the mine strata pressure bumping, but could have an in grade prediction effect of the mine strata pressure bumping danger from the local prediction and regional prediction in space and could have the full monitoring and measuring of the energy from the concentrati on to releasing for the coal and rock fracturing procedure. The practices showed the ARES-5/E ground acoustic emission monitoring and measuring system could have a n early prediction of the mine strata pressure bumping accident;the application of the micro seismic and ground acoustic emission comprehensive monitoring and meas uring technology could have the combined advantages of the two technologies and would have the effects of the mine strata pressure bumping prevention and control.
