摘要

矿震是采矿活动引起的一种诱发地震,与地下岩层移动变形紧密相关。岩层的移动变形能是由垂直应变和水平变形组成的,而矿震能量释放的大小可由岩层移动的变形能来计算,因此,本文提出根据岩层的移动变形分析预测矿震的大小及其分布。现场观测记录的实际矿震发生次数及总能量分布与预测的结果高度吻合,实践证明采用矿山地下岩层移动变形预测矿震有关参数的可能性。
Mineral earthquake,generated by the mining activities,has much to do with the moving deformation of underground mining bed.The capacity of the moving deformation of underground mining bed comprises vertical strain and horizontal one,by which we can calculate the releasing energy of the Mineral earthquake.Consequently,we can analyze the size of pre-estimating Mineral earthquake as well as it's spreading.The highly coincidence of on-spot observation note on actual shock times with the overall energy spreading and the result of pre-estimation proves the possibility of the means that the Mineral earthquake's parameters can be pre-estimated by the moving deformation of underground mining bed.
