摘　　要：通过分析、评价排土场滑坡的危险性及主要影响因素,提出有效的排土场滑坡预防对策。在文献分析和实地调查的基础上,得出排土场安全现状和影响排土场稳定的因素,编制排土场滑坡事故安全检查表来评价排土场的安全状况。采用事故树分析方法得到排土场滑坡事故的原因和主要影响因素。排土场滑坡事故最重要的影响因素是高陡边坡、排水沟失效,其次是排土工艺不合理、堆置高度不合理、长时间降雨和地震。根据分析的结果,制定了预防排土场滑坡事故的有效措施。By analysis and assessment on the risk and major influence factors of dump landslide, this paper puts forward some effective prevention measures for dump landslide. Based on literature analyses and field investigations, mine safety situation and the influence factors of dump stability are obtained and a safety check list for dump landslide accidents is worked out to assess the security status of the dump. By using fault tree analysis, the accident causes and irdluent factors of dump landslide have been obtained. The main influence factors of dump landslide are firstly high and steep dopes and failure of drainage ditches and secondly unreasnable dumping processes, unreasonable stacking height and long time of rain and earthquake. According to the analysis results, the effective measures to prevent dump landslide accidents are put forward.
