摘要
分析首钢铁矿沙厂采区的岩组及岩性、边坡岩体结构等地质特征,并进行工程地质分区。从岩体结构特征分析、结构面和边坡面产状的几何组合关系分析和极限平衡分析确定了边坡岩体的破坏模式。分析评价结果不仅对矿山开采具有重要意义,而且对同类矿山的边坡研究具有借鉴意义。
The engineering geological characteristics of rock type and characteristic, and the slope rock-mass structure in Shachang open pit of Shougang Iron Mine are analyzed, and the engineering geological sub-areas are divide based on the results. The failure model of the slope rock-mass is identified by analyses of rock-mass structural characteristics and geometric compounding relation between structural face and slope structure, and limited equilibrium calculation. The result can be not only applied to direct the mine exploitation, but also referred by the slope research of the similar mine.
