摘　　要：广西小型露天采石场伤亡事故类型的统计分析表明,坍塌和高处坠落事故占全部死亡事故的74%,而高陡边坡开采是导致坍塌和高处坠落伤亡事故的主要因素。采用Rockfall数值软件分析了某典型小型露天采石场高陡边坡滚石的运动轨迹和运动特征,探讨了小型露天采石场高陡边坡发生安全事故的技术原因;并在此基础上提出了针对性的预防措施。Statistical analysis of casualty accident types in small open-pit quarries shows that collapse and high falling accidents account for 74% of all fatalities in Guangxi,and mining high and steep slopes is the main factor leading to collapse and high falling casualties.Rockfall numerical simulation software was used to analyze the motion trajectory and characteristics of the rolling stones on high and steep slopes of a typical small open-pit quarry.Meanwhile,the technical reasons of safety accidents in high and steep slope of small open-pit quarry were discussed.On this basis,the corresponding preventive measures were put forward.
