摘　　要：合理的露天开采境界直接关系到矿山经济效益,而境界的圈定是一项非常复杂的工作。根据某金矿地质资料,利用3DMine软件建立了地表及矿体实体三维模型,在地质资料和实体模型的基础上,运用距离幂次反比法对模型进行品位估值、储量计算,并根据矿床实际的赋存条件、开采技术条件、成本及市场经济特征进行露天开采境界圈定,通过不断优化,得出该矿山的最优露天开采境界。该软件的应用,不仅减轻了设计人员的工作量,同时避免了由于设计人员水平差异造成的误差,对矿山设计和实际生产有现实指导意义。A reasonable boundary of open-pit mining is directly related to mine economic benefit,and the delineation of the boundary is a complex job.Based on the geological data of a gold mine,a three-dimensional solid model of the surface and ore body was built using 3DMine software.Based on the geological data and the solid model,the model was evaluated using the distance power inverse correlation method for grade storage calculation,and the open-pit mining boundary was defined by the actual occurrence conditions of the deposits,technical conditions for development,costs and market economic characteristics,through continuous optimization,to derive the optimal open-pit mining boundary of the mine.The application of the software,which not only alleviates the workload of the designer,but also avoids the error caused by the difference in the designer s level,will have a realistic guidance on mine design and actual production.
