榆阳煤矿升级改造项目水灾害的分析与评价

Analysis and evaluation of water inrush disaster of upgrading reform in Yuyang coal mine

通过对榆阳煤矿升级改造项目矿井水文地质条件概述、大气降水、地表水和地下水的描述,根据该矿水文地质特征和矿井开采方式,分析了矿井水灾害方面存在的主要危险有害因素,并采用预先危险性分析法对矿井水灾害危险度进行分析,采用函数分析法确定了矿井水灾害的危险等级,采用事故树分析法求出事故树的最小割集、事故树的最小径集、事故树的概率重要度、事故树的结构重要度等参数,并对榆阳煤矿3.00Mt/a产业升级改造项目防治矿井水灾害提出对策建议和措施。

By describing hydrogeology condition,meteoric water,surface water and groundwater,this paper analyzes dangerous and harmful factors in the mine water disaster.Preliminary hazard analysis of the mine water disaster is introduced.Risk grade is set up according to function analysis method.Minimal cut sets,minimum path sets,probability importance and structure importance of the accident are obtained.Some suggestions and countermeasures of water inrush disaster of upgrading reform in Yuyang Coal Mine(3.00Mt/a)ar...
