摘要
根据安家岭露天矿确定的最终开采境界,对靠近民用设施开采区域的东边界边坡稳定性进行综合评价,利用瑞典条分法对东边界边坡3个典型剖面进行不同边帮角的计算分析,确定最终的边帮角,使得在保证东部边坡稳定和不影响周围设施的情况下,最大程度的回收煤炭资源,提高生产效益。结果表明:东边界最终帮坡角为34°时,整个东部边坡各个剖面均处于稳定状态,对周围的民用设施影响最小,而且能最大程度的回收煤炭资源。
According to the final mining boundary determined by Anjialing Open-pit Mine,the article comprehensively evaluates the stability of the east boundary slope near the mining area of civil facilities,uses Swedish strip method to calculate and analyze three typical sections of the east boundary slope,and determines the final slope angle,which can make the coal resources be recovered to the maximum extent and the production efficiency can be improved when the eastern slope is stable and does not affect the surrounding facilities The results show that the final slope angle of the eastern boundary is 34°,and the whole eastern slope is in a stable state,the influence on the surrounding civil facilities is minimal,and the coal resources can be recovered to the greatest extent.
