蒙库铁矿边坡岩体质量分级研究

Rockmass quality classification of slope in Mengku iron mine

合理的岩体质量分级是边坡稳定性分析和支护设计的基础。文中根据室内岩石力学试验和岩体结构面的现场量测统计,结合蒙库铁矿开采设计,采用CSMR法对北帮边坡岩体质量进行了系统分级。研究结果表明,该段边坡岩体质量为Ⅱ级,局部可能出现小规模的块体破坏。

Rational rockmass quality classification is the base of slope stability analysis and support design. Based on the laboratory rock mechanical test, rock mass structure plane measurement statistics and the mining design, the rockmass quality classification of the north slope in the mine was carried out. The result was that the quality of the slope rockmass was grade Ⅱ and local block failure might occur.
