露天煤矿基于FLAC^(3D)靠帮开采可行性方案

Feasibility scheme of steep slope mining based on Flac^(3D)

为了最大限度回收煤炭资源,越来越多的露天煤矿采用靠帮开采进行压覆资源回收,以纳林庙灾害治理工程为例,从现状分析、提出方案,到采用FLAC^(3D)三维有限差分程序进行边坡稳定分析论证了端帮角度从37°可以提高至43°,为端帮快速开采、回填提供技术支撑。

In order to maximize the recovery of coal resources, more and more open-pit coal mines adopts steep slope mining pressure resource recovery. Taking Nalinmiao disaster control engineering as an example, from the current situation analysis, scheme to using Flacw three-dimensional finite difference program, the article carries out slope stability analysis and demonstrates end slope angle from 37 degrees to 43 degrees, which provide technical support for fast mining and backfill.
