露天矿非工作帮的设计分两个阶段: ·确定边帮的极限参数——用地质力学计算法确定边帮高度H_пp)和帮坡角α_пp); ·根据非工作台阶和各种用途平台的参数设计边帮。只要满足以下条件,就能保证给定高度边帮的稳定性:α_k≤α_(пp)(α_k——设计的帮坡角)。但是,即使这两个角相等,也不能说明边帮的各参数是最优的,因为还不知道这两个角度是否能满足根据非工作帮剖面确定的露天采矿场境界内剥岩量最小这一准则。众所周知,凸形边帮比平面形边帮经 The design of open-pit non-working billets is divided into two phases: • Determine the limit parameters of the edge • Determine the edge height H_pn and the slope angle α_pn using geomechanical calculations • Based on the non-working steps and the various platforms Parameter design edge help. As long as the following conditions are met, the stability of a given height can be guaranteed: α_k≤α_ (пp) (α_k - designed helix angle). However, even if these two angles are equal, it can not be explained that the parameters of the edge are optimal because it is not yet known whether these two angles satisfy the minimum amount of stripping in the open-cut mining area defined by the non-working profile A guideline. As we all know, convex edge to help than the plane side by
