摘要
爆破地震波在岩层中的传播是一个十分复杂的过程 ,本文通过对爆破地震波传播规律经验公式的分析 ,提出等效距离的概念 ,且认为应根据等效距离的大小来划分爆破地震的影响区域 ,并用实例说明了这一划分方法的可行性。
Propagation of blasting-induced seismic waves in rockmass is a very complicated process. The paper discussed the empirical formula for propagation rules of blasting-induced seismic waves and proposed the concept of equivalent distance. It is the author's view that influence area of blasting seismicity could be divided based on equivalent distance. A case study has proved the feasibility of this division.
