【摘要】 冒落型矿震是一种普遍发生的采空区灾害,正确确定冒落矿震的能量是准确预报矿震强度的前提。为此从上部岩体冒落做功分析着手分析了位势能的转换,分别探讨了影响振动能、破碎能、冲击变形能大小的因素;提出了基于实验室测定位势能转化为振动能转化系数的矿震能量的定量确定思路;并对矿震能量耦合进行了简单探讨。更多还原

【Abstract】 Cave-in type mining tremor is a common disaster in mined-out area.Correct determination of the energy of cave-in type mining tremor is the essential prerequisite for accurate forecasting of mining tremor strength.The transformation from the potential energy into the work done by the cave-in of the upper rockmass is analyzed and the factors affecting the vibration energy,breaking energy and impact deformation energy are discussed.It is proposed to quantify the energy of mining tremor by the coefficient of the transformation from the laboratory-measured potential energy into vibration energy and the energy coupling of mining tremor is investigated in a simple way.更多还原
