摘要
以灵泉露天煤矿为例,研究了提高露天煤矿顶帮边坡废止角的可行性。通过现场勘察和分析研究煤层围岩的岩石物理力学试验成果,确定了顶帮边坡的岩体力学参数,认定了露天顶帮边坡的疏干排水状态,进而对顶帮边坡进行了稳定性计算,并对影响顶帮边坡稳定性的主要因素进行了敏感度分析,提出了保障顶帮边坡稳定性的工程措施。
By the reconnaissance at the site and the analysis of the results of the rock physics mechanics test of the coal seam and country rock, the physics mechanics parameters of the rock and the state of draining off water were found out. then the stability of hangingwall slope was calculated, the susceptibility of main factors to the slope stability was analyzed and the measures of slope stability were set forth.
