摘要
介绍了三山岛金矿新立矿区微震监测系统的组成及网络布置。基于对多微震事件数据的处理,研究了波形的分析方法;依据波形与生产活动的对应关系,对检测到事件的波形进行了分类研究,确保了事件的及时识别和分类保存。基于量化的地震参数,特别是利用等值线、回归曲线和时间变化曲线与采矿活动的对应关系,为井下矿山巷道和矿柱破坏预报以及破坏的预测研究提供了一种新方法。
The composition and network layout of seismic monitoring system in Xinli mining area of Sanshandao gold mine was introduced. Based on the seismic event data processing, the analysis method was studied. According to the corresponding relationship of waveform and production activity, the waveform of detect events classification was studies. And it can ensure the recognition on time and the event classification preservation. Based on the quantitative earthquake parame- ters, especially the application of contours, regression curve and time variation curve and the corresponding relation, it provides a new method for forecasting the failure of underground mining tunnels and the pillar.
