【摘要】 据计算，峨口铁矿边坡如增加１°坡角可减少剥离量５６８４万吨，节约经费１．７亿元。在地质调查基础上，应用三维物理模型对峨口铁矿边坡进行了设计最终边坡角开挖试验，加陡边坡角以及陡帮强采试验研究，以进一步验证矿山原设计最终边坡角的合理与否。更多还原

【Abstract】 On the base of geological prospecting, a three dimensional physical model is used in experimental study of the stability of high steep slope in consideration of different slope angles and the power excavation of the slope. It further proves the rationality of previous design angles for the mine slope.更多还原
