摘　　要：在莫桑比克北部6678L石墨矿的矿岩性质和有限的工程岩土数据的基础上,根据矿岩的单轴抗压强度,采用MRMR采矿岩体分类系统确定露天采场的最终边坡角,进行相应的边坡研究;采用露天矿山境界优化软件建立模型,通过技术经济比较最终确定矿山合理的建设规模;并根据矿山采选方案确定的技术经济指标,进行了境界优化,确定了经济合理的露天开采境界。Based on the rock properties and limited engineering geotechnical data of 6678l graphite mine in northern Mozambique,according to the uniaxial compressive strength of rock,the article adopts Mining Rock Mass Rating to determine the final slope angle of open-pit mine,and studies the corresponding slope.The article determines the reasonable construction scale of the mine through detailed technical and economic comparison by using the strategic mine planning software.Finally,according to the technical and economic indicators determined by the mining and processing scheme,the mine optimizes boundary and determines the economic and reasonable open-pit mining boundary.
