【摘要】 从湖南的矿山地震的基本情况出发,对近年来发生在不同矿区的几个典型震例进行综合分析后认为:矿震的生成不仅与开采形成的重力场有关,还与断裂构造的原岩构造应力和现今应力场有关。矿震的发生频度和震级的大小,除与矿区的地质构造有关外,主要与开采的深度、强度和方法有关。更多还原

【Abstract】 Based on the basic situation of ore earthquakes in Hunan,we made comprehensive analyses on ore earthquakes occurred in several different mine areas in recent years.The results show that the occurrence of ore earthquake is not only related to the gravity field formed by the exploitation but also related to the original rock structural stress and present stress field of the fracture structure.The frequence and magnitude of ore earthquakes are mainly related to mining depth,intensity and method,in addition to related to the geological structure of the mining area.更多还原
