摘要
针对玲南金矿遗留采空区和岩爆现象,采用微震监测技术,对深部采场开挖过程微震活动特征进行研究。综合实际工程条件和传感器对角空间网络方案,建立数字化多通道微震监测系统,该系统具有先进、丰富的地震学定量分析和可视化功能,可以对井下的岩石活动情况进行研究,并在岩体波形变化的基础上进行分析。研究结果可以为更好地理解和分析复杂应力条件下的岩石变形及其微震活动性诱发失稳机制提供重要的参考。
Aimed at goaf and rock burst phenomenon in Lingnan Gold Mine, the seismic activity characteristics of deep excavation process are studied withmicroseismic monitoring technology. Consideration practical engineering conditions and sensor diagonal space network solution, digital multi-channel seismic monitoring system is estab- lished, which has the function of advanced and rich seismology quantitative analysis, and the rock activities can be studied. It is analyzed based on the waveform changes of rock mass. The results of the study provides important reference for better understanding and analyzing the rock deformation under complicated stress conditions and the mechanism of instability induced by their seismic activity.
