摘要 为确保安太堡露天矿进入芦子沟背斜区期末内排土场不发生顺层滑坡的安全生产事故,从而保证背斜区附近作业人员和设备安全;基于安太堡矿过背斜区期末的地质构造、排土现状和岩土物理力学性质,采用极限平衡法对背斜区内排土场边坡进行了边坡稳定性分析。结果表明:内排边坡整体稳定,局部区域处于基本稳定。结合现场边坡监测数据、巡查情况,对基本稳定区提出了相应治理措施,使安太堡矿过背斜期末的内排土工程实现了安全生产,降低了运输成本,进一步提高了设备效率。 In order to ensure the safety production accident of bedding landslide not happen at the end of the period when Antaibao Open-pit Mine enters Luzigou anticline area,thus ensuring the safety of workers and equipment near the anticline area,based on the geological structure,the present situation of soil dumping and the physical and mechanical properties of rock and soil at the end of the period in the anticline area of Antaibao mine,the article analyzes slope stability of the dump slope in the anticline area by the limit equilibrium method.The results show that the internal slope is stable as a whole and the local area is basically stable.At the same time,combining with the on-site slope monitoring data and the inspection situation,the article puts forward the corresponding control measures for the basic stable area,so that the internal dumping project at the end of the overanticline period in Antaibao mine can achieve safe production,reduce the transportation cost and improve the efficiency of the equipment.
