摘　　要：岳城煤矿3号煤层2301,2302工作面(Ⅲ2301,Ⅲ2302工作面)北侧开采边界上方存在一近东西走向的高陡边坡,坡底为一个居民小区,小区内建设有多栋6层居民楼及其他附属建筑设施。为有效开采煤炭资源,同时保护人民的生命财产安全,以Ⅲ2301,Ⅲ2302工作面为研究对象,运用FLAC3D计算软件建立模型,模拟Ⅲ2301,Ⅲ2302工作面分层开采对高陡边坡及下方建筑的影响程度及影响范围,采用边坡稳定性分析理论,分析高陡边坡失稳的可能性,并提出相关工作建议。There is a high and steep slope with nearly east-west trend above the mining boundary on the north side ofⅢ2301 andⅢ2302 working face of No.3 coal seam in Yuecheng Coal Mine.At the bottom of the slope is a residential community,in which there are many 6-storey residential buildings and other ancillary building facilities.In order to exploit coal resources effec-tively and protect people's life and property safety,takingⅢ2301 andⅢ2302 working face as the research object,this paper simulated the impact degree and scope of slicing mining ofⅢ2301 andⅢ2302 working face on the high and steep slope and the buildings below by using FLAC3D software to establish the model,analyzed the instability possibility of high and steep slope by using the slope stability analysis theory,and put forward relevant work recommendations.
