摘　　要：井下泥石流是自然崩落法开采矿山常见灾害,对矿山安全生产和矿石贫化有重大影响。研究了矿山已经发生的九次井下泥石流与矿区地形地貌、第四系冰碛物厚度、断层构造、出矿推进方向、放出矿量、发生时间等的关系,分析了泥石流的物质组成,对井下泥石流产生的物源条件提出了一些新的观点,优化了井下泥石流致灾机理,并对井下泥石流防治提出了建议,研究成果对矿山井下泥石流的治理工作及安全生产可提供有益借鉴。Underground debris flow is a common disaster caused by the natural caving mining method,it has a significant effect on safety mining operations and ore dilution.Nine underground debris flows have occurred in the mine,so we analyzed the relationships among underground debris flows and the topography and landforms of the mining area,the quaternary glacial material thickness,the fault structure,the ore drawing direction,the ore output,the occurrence time,and so on,the paper analyzed the material compositions of debris flow,and made some new points of formative materials sources of underground debris flow,and it optimizes the disaster-causing mechanism of underground debris flow,so it proposed recommendations for underground debris flow,the research results can provide a useful reference to the management of the underground debris flow of the mine.
