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。
This paper analyzes the geologic characteristics of rock group, lithology and rock mass structure in the mining area of Shougang Iron Mine, and carries out engineering geological zoning. From the analysis of rock mass structural features, geometrical combination of structural plane and side-slope geometry and limit equilibrium analysis, the failure mode of slope rock mass is determined. Analysis and evaluation of the results not only of great significance for the mining, but also for the same kind of mine slope research for reference.
