微震事件的多参数信息监测岩爆技术研究

基于微震事件单个参数信息对岩爆进行监测,都存在相对应的局限性。结合中矿金业玲南金矿岩爆发生的情况,通过建立微震监测系统,并利用微震系统采集的监测事件参数信息中的微震事件分布规律、微震事件震级与频率关系和微震事件的能量与地震矩分布规律等,对18~22中段的掘进和回采过程中的岩爆活动规律进行综合分析,监测分析结果在现场应用效果良好。

Study on rockburst monitoring technology through multi-parameter information of micro-seismic events

There are corresponding limitations on rock burst monitoring which is monitored by Single parameter information of microseismic events. Under the circumstances of rockburst in Ling nan Gold Mine , through the establishment of microseismic monitoring system, the distribution of microseismic events, the relationship between the magnitude and frequency distribution and the distribution of energy and seismic moment of microseismic events have been used in the rock burst which has happened in the tunneling and mining process in the 18-22 segment. Monitoring results have been got a good application.in the research site.
