摘　　要：为有利于矿震灾害的预测、预防和治理,针对目前矿震各种分类间尚未建立起相互联系体系的现状,应用该灾害机制的最新研究成果,按照有利于对症治理灾害的原则,照顾到已被普通接受的习惯,提出矿震层级分类的概念、原则和优越性。按照矿震发生受原生构造应力场作用方式、岩石介质物理力学性质及岩层力学结构对矿震的控制作用、矿震与采矿活动的相关性、次生应力场动力来源和矿震发生及破坏的部位分出5个层级16种矿震类型,强调区域构造应力场和开挖造成的岩体应力状态改变在矿震分类、研究和治理中作用的重要。Currently,the different methods for classification of mining-induced seismicity have no relation with each other.In order to be convenient for prediction,prevention and control of the mining-induced seismicity,based on the latest research results on the mechanism of the disasters,the classification of mining-induced seismicity is presented in this paper,following the principles of benefiting disaster prevention and control and non-conflicting to practices adopted both at home and abroad.The concept,principle and advantages of the hiberarchy classification of the mining-induced seismicity are given.5 classes and 16 types of mining-induced seismic events are classified based on the influence of in-situ tectonic stress field,physical and mechanical properties of rocks,rock mass structures,correlation between seismicity and mining activity,source of mining-induced stress change,and the locations of seismic sources and rock mass failure.The importance of regional tectonic stress field and stress change due to mining is emphasized in the mining-induced seismicity classification,research,and control.
