摘　　要：断裂构造是矿山地质动力现象显现的一个重要地质因素。以口泉断裂为研究对象,在分析其宏观特性和运动机制的基础上,采用数值模拟方法对口泉断裂作用下的煤体应力分布进行研究,分析口泉断裂与大同矿区东部井田开采矿压显现的关系。研究表明:口泉断裂的水平挤压和垂直升降对大同矿区的煤层的应力环境都有较大影响,其对周围岩体的稳定性及应力场的影响将会更加显著,口泉断裂对大同矿区东部的忻州窑矿、煤峪口矿、同家梁等煤矿在煤层开采过程中的矿压显现具有重要的影响和控制作用。Fracture structure is an important geological factor for geological dynamic phenomena. Based on the anal- ysis of macroscopic characteristics and movement mechanism, the stress distribution under the action of the Kouquan fault is studied by numerical simulation. The relationship between the Kouquan fault and the underground mining in the east of Datong mining area is analyzed. The result shows that the horizontal and vertical movements of the Kouquan fault have great influence on the stress environment of the coal seam in Datong mining area, and the influence on the stability and stress field of the surrounding rock mass will be more obvious. The Kouquan fault have important influence and con- trol effect in the process of mining of Xinzhouyao mine, Meiyukou mine and Tongjialiang mine
