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 new perspective, the paper focuses on the relationship between the overlying conglomerate movement and the rockburst in Huafeng mine in Shandong Province, and summarizes the inherent regularity between the two. It points out that the surface subsidence of Huafeng mine is essentially Which reflects the law of the overlying conglomerate movement. The relationship between the surface subsidence velocity and the rock burst pressure, the periodicity of the surface subsidence velocity and the period of the rockburst has a certain corresponding relationship, and the rebound effect of the surface subsidence velocity , Large period, small period, period self-similarity and so on. Finally, the feasibility of a new method of predicting and controlling rock burst with surface subsidence as monitoring index is pointed out. The reference significance.
