地下矿山空区塌落产生震动的实验与计算

Experiment and Calculation of Vibration in the Roof Caving of Underground Mine Cavity

地下矿山采空区顶板塌落时,塌落体冲击空区底板会产生地震波,冲击地震波会对空区附近的建(构)筑物及设施产生一定的影响。针对目前一些地下矿山大面积空区长期未进行处理可能遇到的相同问题,采用模拟实验的方法,对实验得到的数据进行分析计算,得出塌落震动的传播规律,为震动影响评估提供理论参考。

The shock wave produced by the roof caving against the bottom in underground mine cavity will have impact on the nearby structures and facilities. In view of such problem that may occur in some large underground mine cavities that haven＇t been treated for a long time, a simulation experiment was made. From the analysis of the experiment data calculation, the propagating law of caving-caused vibration was drawn, providing a theoretical reference to the evaluation of vibration impact.
