摘　　要：通过对象山煤矿水文地质条件的分析,认为奥陶系石灰岩引起的矿井突水主要集中在上马家沟组2段和3段,突水时水量由小变大,突水点分布于井田边浅部地层倾角由陡变缓的转折带上,突水与断裂构造有密切关系,引发突水的断层及裂隙走向多为NNE,倾向SEE.Through analysis of the hydrogeological condition analysis of Xiangshan coalmine, considered that Water Inrush of Ordovieian carbonate rock （ Majiagou Formation） was mainly concentrated in the second and third section, the amount of inrushing water was becoming from less to large, and the position of water Inrush of Ordovician limestone distributed in the edge of mining upper level conner, the study indicates that the case have relationship with the fault structure of formation, and the great mass stricke of the fault and cranny towards NNE and tendency to SEE.
