【摘要】 冬瓜山铜矿是千米深井开采有岩爆倾向的金属矿山,建立了微震监测系统以实现岩层活动的连续监测和岩爆的实时预报。综合实际工程条件和拟定传感器空间网络方案的地震事件定位精度和系统灵敏度计算结果,实现了微震监测网络的优化。建立的数字化多通道微震监测系统具有先进和丰富的地震学定量分析和可视化解释功能,可以完成多重聚类和时间序列分析。在冬瓜山铜矿已记录的监测数据的基础上,开展了矿山地震信号识别、矿山地震活动分析方法和冬瓜山地震活动规律等研究,取得到了初步成果。更多还原

【Abstract】 Dongguashan Copper Mine,a thousand meter-deep underground metal mine with rockburst proneness,has established the microseismicity monitoring system for the realization of a continuous monitoring of rock strata and real-time rockburst prediction.The optimization of the microseismicity monitoring network is realized by comprehensively considering the real engineering conditions and the calculation results of the seismic event positioning accuracy and system sensitivity of the proposed transducer space network alternatives.The established digitalized multi-channel microseismicity monitoring system has advanced and plentiful seismological quantitative analysis and visualization interpretation functions that are capable of multi-clustering and time sequence analysis.Based on the monitoring data recorded in Dongguashan Copper Mine,research was carried out on the mine seismic signal identification,analysis method and seismicity law,in which preliminary achievements have been obtained.更多还原
