摘要
根据煤或岩体的赋存特征及采动后的受力特点，将采矿及掘进等工程进行过程中诱发的地震灾害分为三类，即完整煤岩体受压应力作用的失稳、顶底板受拉应力型地震及断层走滑受剪型诱发地震。文章在分别分析其成因的基础上，研究了采矿诱发三种类型地震的发生条件，提出了防治发生诱发地震的对策。
ccording to the characteristics of the existence of coal or rock body and their state subjectedto forces,earthquake caused by underground mining and excavation are duvided into 3 catalogs inthe paper- - one is the type of unstability of the coal or rock boby under pressing stress,one isgliding of fault under shear stress. On the basis of analyzing their reasons, the situations are stated for the happening of the 3 types of earthquakes led by mining activities. The strategy for theprevention of this kind of earthquake is offered in the end.
