摘　　要：针对国内部分地下矿山开采过程中频频发生泥石流事故,在开展较为系统的调查与统计基础上,结合具体矿山,初步分析了井下泥石流的发生机理,指出固体物质、采矿活动及地质因素和降雨是形成泥石流的3个必备条件,对井下泥石流形成过程进行了论述,提出了相应的工程控制措施,并对今后井下泥石流研究的方向和内容提出了建议。In view of the frequent occurrence of the mud-rock flow accidents in some domestic underground mines and based on a systematic investigation and statistics, the mechanism of the occurrence of underground mud-rock flow is analyzed in a preliminary way for some specific mines, It is pointed out that solid substance origin, mining activity, and geological factors and rainfall are the three necessities for the formation of mud-rock flow. Correspondent engineering control measures are put forward and suggestions on the direction and contents of the future research on underground mud-rock flow are made.

关 键 词：井下泥石流 机理分析 控制措施
