云浮硫铁矿是化工矿山的一个大型露天矿。目前矿区基建工程已基本结束,即将投入生产。 乌石岭滑坡体治理工程,是属于露天采场外围工程。该滑坡体位于露天采场东帮乌石岭沟谷上游北坡,乌石岭沟长约1公里,沟谷纵坡比较大。滑坡体高差110米,沿走向长140余米,塌方量约30万立方米。滑坡区段坡面呈波浪形,滑壁断裂明显,为阶梯状,滑坡体有不同的滑动方向,且有滑坡梁存在,曾发生过多次滑坡。见图1
Yunfu Pyrite Mine is a large chemical mine opencast mine. At present, mining infrastructure projects have basically ended, about to put into production. Wushi Ling landslide treatment works, is outside the open pit mining project. The landslide body is located in the open pit to the east of Wushi Ling Valley north slope, about 1 km long Wushi Linggou, the valley longitudinal slope is relatively large. Landslide height difference of 110 meters, along the direction of more than 140 meters, about 300000 cubic meters of collapse. The slope of the landslide section is wavy, the sliding wall is obviously broken and has a staircase shape. The landslide body has different sliding directions, and the landslide beam exists. There have been many landslides. see picture 1
