摘要
以云南小龙潭煤矿沼坝露天龙桥排上场为研究实例,首先介绍了排上场基底的地质条件和排弃物的物理力学特性.然后对排上场边坡的稳定性进行了分析和评价,着重讨论了稀湿物料的产生和倾斜基底条件下边坡破坏的机理,最后提出了预防和治理龙桥排上场失稳的综合措施.
At first,this paper presents geological conditions of the waste dump base and the mechanical characteristics of waste materials.Then the stability of the waste dump is analyzed and evaluated .The reasons the waste materials convert from the plastic state at pit into the flowing state at the dump in the course of being transported by belt conveyer and the mechanism of dump slope failure have been studied in particular.Finally,the methods of prevention and cure of the waste dump failure have been put forward.
