摘要
通过对庙沟铁矿边坡进行现场原位试验与边坡风化破碎带测试、边坡结构面调查、岩体质量评价、边坡岩体强度参数及岩体强度指标反演分析、边坡稳定性计算,提出了庙沟铁矿露天最终边坡角可由原设计48°进一步提高到52°,并进行经济效果分析。
Through the site in situ test,slope weathering fracture zone test,slope structural plane investigation,rock mass quality evaluation,slope rock mass strength parameter analysis,rock mass strength index back analysis and slope stability calculation were done on Miaogou Iron Mine slope,open pit final slope angle of Miaogou Iron Mine could increase from original design 48° to 52° was proposed,and economic effect was analyzed.
