摘　　要：矿山地震,又称为"矿震",是深井开采中的地质灾害。它具有震源浅,震级小,烈度大,破坏性强等特点。文章基于地球动力区划的理论和方法,以北票台吉矿的实际研究资料为例,对地质动力引起的矿山灾害及矿震的发生规律进行了研究。认为"矿震"的发生是受区域构造应力场的影响,与地下采矿活动密切相关的一种地质动力突变现象,一般发生在地质构造比较复杂、断裂新活动比较显著的地区。文中还讨论了矿山地质动力的作用特征、井下活动断裂的变形与错动规律和对岩层与地表移动的影响。研究了"矿震"的震源机制、断裂错动及其与构造应力场和区域地方震之间的关系。Earthquake broken in mine is called mine quake. It is a new geologic hazard in underground mining. It has some characters such as shallow epicenter but great intensity, small grade but strong destroy and so on. Based on the theory and method of geodynamic section division, by taking the practical data of Beipiao mine for example, geological hazard and mine quake affected by geodynamic were studied. A view was presented that mine quake is a geologic dynamic phenomenon affected by regional stress activity. And it has a direct bearing on underground mining. Generally, it takes place at the region of geologic structure more complex and faults activity more obvious. The effect characters of mine geologic dynamic, the law of deformation and break of underground active faults, its effect to movement of rock strata and ground, break pattern of mine quake and the relationship between mine quake and regional stress field ware described in this paper.
