采用 UDEC 软件对平朔东露天矿台阶安全距离进行了模拟研究,通过工况分析确定了设备载荷作用下露天矿台阶边坡的潜在垮落形式,分别建立了平朔东露天矿岩石剥离台阶和排土机排弃台阶的安全距离 UDEC 软件分析模型.数值模拟结果表明,剥离台阶电铲作业的安全距离为12 m,台阶下设备和人员的安全距离为9 m；排弃台阶高度为25 m时,排土机的安全距离为12 m.

The safe distance for Pingshuo Eastern Open-pit bench was simulated by UDEC software?? Based on the operating conditions,the potential caving mode of bench slop was deter-mined under the action of load,and the model of safe distance between rock stripping bench and spreader dump bench was set up by UDEC software?? The simulated results showed that the safe distances should be 12 m and 9m for excavator at stripping bench and equipments and personnel at the bottom of bench,respectively?? When the stripping bench is 25 m in height,the safe dis-tance for spreader should be 12 m.
