某露天矿边坡稳定性分析与隐患治理研究
|
摘要
矿产资源是国家经济发展的物资基础,其开采方式可大致分为露天开采和地下开采。在我国,露天开采的矿产资源占矿产资源开采的70%左右,铁矿石产量的85%来自于露天开采,建材矿山几乎全部采用露天开采。露天矿边坡作为露天矿开采的重要构成要素之一,其稳定性问题一直是露天矿安全开采的难题。本文以四川省攀枝花铁矿朱兰采场狮子山边坡为例,通过现场踏勘测绘,充分认识滑坡范围和滑面形态以及组成边坡岩体的物理力学参数,通过稳定计算分析,提出边坡治理措施。
Mineral resources are the material basis of national economic development,and their mining methods can be roughly divided into open-pit mining and underground mining. In China,open-pit mining accounts for about70% of mineral resources mining,85% of iron ore production comes from open-pit mining,and almost all building materials mines are open-pit mining. Open-pit slope is one of the important elements of open-pit mining,and its stability has always been a problem of open-pit mining safety. Taking the Shizishan slope of Zhulan stope of Panzhihua Iron Mine in Sichuan Province as an example,through on-site survey and mapping,the scope of the landslide and the shape of the sliding surface as well as the physical and mechanical parameters of the rock mass of the slope were fully understood. Through stability calculation and analysis,the slope control measures were put forward.
