摘要
针对胜利东二号露天矿首采区西推方案及西北推方案的边坡稳定问题,结合现场揭露的泥岩弱层等工程地质情况,建立了西推、西北推方案中各端帮、非工作帮不同帮坡角条件下的边坡计算模型,利用极限平衡法进行边坡稳定性计算,得出2种方案各帮在不同帮坡角条件下的边坡稳定性系数。
According to the slope stability problems of propulsion plans towards west or northwest in Shengli No.2 Open-pit Coal Mine first mining area, combining the geological conditions such as the revealed mudstone weak layer, the author establishes slope calculation models under the different slope angle during the western and northwestern propulsion plans, uses limit equilibrium method to carry out slope stability calculation, and obtains the slope stability factor of each slope under the condition of different angle.
