| 摘 要： | 为保证回采灵泉露天煤矿F4断层煤壁的边坡稳定,研究分析灵泉露天煤矿F4断层煤壁的现场考察与露天煤矿地质资料及边坡稳定性监测等资料,确定F4煤壁回采方案,即单斗铲-汽车工艺,采用横采内排,沿煤层走向推进的开采方案.并对F4煤壁回采过程边坡稳定性进行分析研究,结果表明:过F4断层最大边坡高度72 m时,其稳定系数为1.18,回采F4煤壁过程边坡是稳定的,灵泉露天煤矿F4煤壁回采可行.

| Abstract: | Aimed at ensuring the slope stability of the F4 fault coal wall,this paper gives an on-the-spot investigation in Lingquan open coal mine,and an analysis of the geological data of opencast mine and monitoring data of slope stability etc,and offers a definite plan of the F4 coal wall mining,namely,single digger-tip truck processes,meaning the adoption of the plan of horizontal mining and inside dumping to head for mining alone the coal seam.The paper gives an analysis of slope stability in the process of F4 c... |
