摘要
水厂铁矿露天边坡工程研究是国家“七·五”攻关项目。本文对其主要研究内容、研究方法特点以及取得的结果进行了全面阐述。研究结果表明,与原设计相比,总体边坡角可提高2—3°,增加采出矿石量379万t,减少废石剥离量7228万t,取得1.7903亿元的经济效益。
The rock slope engineering at Shui chang Open Pit Iron Ore Mine is one of '7.5'national projects. In this paper the main objects and methodology of investigation and the results obtained are described. The results indicated that it is feasible to use a total slope angle 2-3° higher than the original design, thus increasing the excavated ore quantities by 3.79 million tonne and decreasing the stripped waste by 72.28 million tonne. An economic benefit of RMB179.03 million Yuan is expected.
