矿山震动是由于开采活动使得上覆岩层运动造成的 ,因此 ,可以根据岩层的运动变形分析预计矿山震动的大小及其分布。岩体的变形能是由垂直应变和形变组成的 ,而矿震能量释放的大小可由岩体运动的变形能来计算。现场观测的实际矿震能量分布与预计的结果非常吻合 ,说明采用岩层变形预计矿山震动的可能性
The mine vibration is caused by the overlying strata movement caused by the mining activity. Therefore, the size and distribution of the mine vibration can be predicted according to the deformation analysis of the strata. The deformation energy of rock mass is composed of vertical strain and deformation, and the magnitude of the release of rock mass energy can be calculated by the deformation energy of rock mass movement. The actual energy distribution of the observed earthquakes in the field is in good agreement with the predicted result, indicating the possibility of using mine strata to predict the mine vibration
