摘　　要：对采矿业而言,传统的二维信息化方式己经不能满足矿山发展的需要,在三维环境下进行矿山生产设计和管理己成为必然趋势,同时也是实现数字矿山建设的基础性技术。智能矿山生态建立的重要组成部分是矿山三维地质建模,结合三维模型和储量计算,设计了包括境界优化、开采设计、爆破设计及矿石平衡环节的采剥管理流程,阐述了各环节的作用及必要性,着重研究了境界优化的2种常用算法,即浮动圆锥法与LG图论法。设计的露天矿山三维模型与采剥管理系统能为矿山生产提供更精准全面的指导信息,提高各业务部门的信息融合与协同能力,帮助矿山更高效、安全、合理地生产。For the mining industry,the traditional two-dimensional information approach has failed to meet the development needs of mines,and the design and management of mine production in a three-dimensional environment has become an inevitable trend and is a fundamental technology to realize the construction of digital mines.An important part of the establishment of intelligent mine ecology is 3D geological modeling of mine.This paper combines 3D modeling and reserve calculation to design a mining and stripping management process that includes ultimate pit limit optimization,mining design,blasting design,and ore balance,and explains the role and necessity of each process.The principles of 2 common algorithms of floating cone method and Lerchs-Grossman graph theory for ultimate pit limit optimization are studied emphatically.The 3D modeling and stripping management system of open-pit mines designed in this paper can provide more accurate and comprehensive guidance information for mine production,improve the information integration and synergy of various business departments,and help to realize more efficient,safe and rational production of mines.
