上覆砾岩运动与冲击矿压的关系研究

Studies on forecasting rock - burst according to rock mass movement

从全新角度出发,以山东华丰矿上覆砾岩运动与发生冲击矿压的关系为研究重点进行了理论分析,总结了两者之间的内在规律性,指出华丰矿地表下沉实质上即反映了上覆砾岩运动的规律,其地表下沉速度与冲击矿压、地表下沉速度周期性与冲击矿压的周期发生具有一定的对应关系,并首次提出地表下沉速度的反弹效应、大周期、小周期、周期自相似性等规律现象,最后指出了以地表下沉速度为监测指标的新的冲击矿压预测与防治方法的可行性,对开采引发冲击矿压预测研究具有一定的借鉴意义。

From a novel view, the inner rules between rock mass movement and rock-burst of Huafeng Mine are summarized and analyzed in this paper. It points out that there is a basic corresponding relationship between sruface subsidence velocity and rock-burst, which has inverse-spring effect, wave band effect, lagging character, he rules of the relationship was summarized. Numerical analysis is calculated, which will contribute to the prevention of rock-burst. The conclusion of academic analysis and numerical simulation will play roles in rock - burst research in future.
