基于事故树分析法的矿山透水风险评价分析

Analysis on the Risk Evaluation of Mine Water Inrush Based on Fault Tree Analysis Method

我国多数矿山水文地质条件复杂,近年来矿山突水事故频发,已造成严重的人员伤亡及财产损失,有必要对引起矿山突水事故的原因进行深入分析。运用事故树分析法,以湖南有色柿竹园多金属矿为例,建立了矿山突水事故树模型,分析了引发突水事故的各种因素,对该矿发生突水事故的风险进行了评价。通过结构重要度分析,确定了矿井水灾害防治的关键:设置排水巷道;实地勘测,定期检查防排水设备及排水巷道,全面掌握矿山空区及掘进情况;制定合理有效的应急预案,设计合理的避灾路线。

The hydrogeological conditions of the most mines in our country are complex,in recent yeras,the mine water inrush accidents outbreak frequently,enormous casualties and property loss are caused,so,it is necessary to analyze the cause of mine water inrush accidents. Take the Shizhuyuan polymetallic mine as the research object,the fault tree analysis method is adopted to establish the fault tress model of mine water inrush accidents. The risk of inrush accident of Shizhuyuan polymetallic mine is evaluated by analyzing the all factors influencing the inrush accidents. By conducting structure importance degree analysis,the preventing and controlling method of the mine water disasters are determined,they are including setting the drainage roadway,conducting filed survey so as to check the waterproof and drainage equipments and drainage tunnels to make understanding of mining zone and driving conditions comprehensively,formulating rational and effective emergency plans and designing reasonable route to avoid disasters.
