一、露天矿边坡加固的意义一般露天矿开采初期,很少出现边坡滑坡,边坡加固也就不足引起矿山工作者的重视。然而,从露天矿开始形成边坡之后,由于改变了边坡岩体的原来平衡条件,就已经存在着边坡变形、破坏和滑坡的潜在因素,并开始了变形破坏的渐变过程。随着边坡不断扩大和延深,使露天矿边坡在某一区段的边坡岩体可能出现边坡变形的突变。这种边坡变形的突变规模,从小到大、从局部到某一区段,以至遍及几个台阶边 First, the significance of surface mine slope reinforcement Generally open pit mining initial stage, there is little slope landslide, slope reinforcement also caused less attention of mine workers. However, after the formation of the slope from the open-pit mine, due to the change of the original equilibrium conditions of the slope rock mass, there are already potential factors of deformation, failure and landslide of the slope and the gradual deformation process begins. With the continuous expansion and deepening of the slope, the slope deformation may occur in the slope rock mass in a certain section of the open pit slope. This sudden deformation of the slope of the scale, from small to large, from local to a section, and even across several steps
