针对复杂埋藏环境下的矿山突水灾害评价难题开展研究通过理论分析,给出了地下渗流场对矿岩稳定性的影响机理;结合理论分析,概述了矿山突水灾害评价的有限元法;面向工程实例,采用ANSYS对南洺河铁矿开采过程中的突水灾害进行评价,预测了矿区内突水危险源区域研究表明,采用基于渗流理论的矿山突水灾害评价的有限元法进行区内突水危险源辨识是可行的.%The research is carried out aiming at the hard water inrush hazard evaluation in mines with the complex buried environment. Through theoretical analysis, this paper gives the influence mechanism of underground seepage field on rock mass stabilitysummarizes the finite element method ( FEM ) for evaluating the water inrush hazard in combination with the theoretical analysisand evaluates the water inrush hazard in the process of mining of Nanminghe Mine by means of ANSYS according to the project case, and predicts the region of water inrush hazard source. The results indicate that it is reasonable to adopt the FEM for evaluating water inrush hazard based on the seepage theory to identify the water inrush hazard source.
