摘　　要：本文应用Geostudio-Slope/W软件和二维刚体极限平衡—Morgenstern-Price法稳定性分析了山西某露天煤矿端帮原设计边坡。山西某露天煤矿南端帮与东端帮各剖面边坡稳定系数Fs>1.2,满足安全储备系数要求,具备陡帮开采条件。基于该露天煤矿端帮陡帮形态设计、端帮陡帮首采区开采境界,根据2023年度原煤产量计划、计划生产剥采比、临时用地与复垦计划、端帮陡帮内排追踪压帮距离等,设计了端帮陡帮开采采排方案,经济效益显著。This paper applies Geostudio-Slope/W software and the two-dimensional rigid body limit equilibrium MorgensternPrice method to analyze the stability of the originally designed end slope of an open-pit coal mine in Shanxi.The stability coefficient Fs of the slopes in the southern and eastern sections of a certain open-pit coal mine in Shanxi is greater than 1.2,which meets the safety reserve factor requirements and meets the conditions for steep slope mining.Based on the shape design of the end slope and steep slope of the open-pit coal mine,the mining boundary of the first mining area of the end slope and steep slope,and based on the 2023 raw coal production plan,planned production stripping ratio,temporary land use and reclamation plan,and the tracking and pressing distance of the end slope and steep slope inner drainage,a mining and drainage plan for the end slope and steep slope has been designed,with significant economic benefits.
