深井矿山岩爆控制体系构建

    Establishment of rockburst control system in deep level mining

    • 摘要: 随着矿山开采深度的增加,原岩应力水平大大提高,导致岩爆等灾害发生频率提高,矿山生产的安全性下降。以微震监测技术为中心构建深井采矿岩爆控制体系,可以提高有岩爆危险和/或危害矿山采矿的安全性。以微震监测系统为中心的岩爆控制体系主要包括:微震监测网络的建立、微震事件波形的处理、微震事件震源参数的量化、回采过程中微震震源参数变化的规律分析、危险区域的识别、危险震级的有效预测、采矿策略的调整和最佳策略的确定。

       

      Abstract: With the increase of mining depth, pre-mining rock stresses increase dramatically, which leads to the rise of the frequency of rock burst occurrence and the drop of mine safety. Base on the micro-seismic monitoring technology, the setting-up of the rockburst control system in deep level mining can improve the safety of mines with rockburst proneness or rockburst hazard. The control system discussed in this paper includes: establishing a micro-seismic monitoring network, processing the micro-seismic event waveforms, digitizing the micro-seismic event source parameters, analyzing the change rules and models of the source parameters during mining, identifying hazard areas and the hazardous magnitude, adjusting and adopting an appropriate mining strategy accordingly.
