摘    要：本文运用波动理论所确定的弹性及粘弹性介质的波动方程,分析推导了P波和S波的传播速度与衰减系数公式,探讨了矿岩散体中波的传播规律及波动机械能的表达式,并对振能在矿岩散体中衰减的原因进行了较全面的剖析。理论分析与有关试验结果得到了相互印证。

Abstract: Based on the wave equations of elastic and viscoelastic medium, the for-mulas of propagation velocity and attenuation coefficient of P wave and S wavehave been analysed and calculated, and the propagation regularity and theformula of mechanical energy of vibration wave in the broken ore have alsobeen studied. The reasons of vibration energy attenuation in the brokenore have been examined completely. The results of theoretic analyses areverified by experiment results very well.
