摘　　要：通过对金山店铁矿井下泥石流的采样分析,进行井下泥石流的颗粒组成以及流动性实验,研究井下泥石流在未被外界扰动条件下的启动条件。研究结果表明地表黄泥及粉矿是井下泥石流形成的物源条件,含水率对泥石流流动性的影响呈现一个先降低后升高的过程。Through the sampling and analysis of the underground debris flow in Jinshandian Iron Ore Mine,size composition and fluidity experiments of the underground debris flow are carried out to study the starting conditions of the underground debris flow without external disturbance.The research results show that:yellow mud and ore fines on the ground are the sources for the formation of underground debris flow,and the influence of water content on the fluidity of debris flow presents a process where it first decreases and then increases.

关 键 词：井下泥石流 流动性 启动条件
