摘要
金属矿床地下开采形成的大量采空区不仅危及矿山的安全,而且对资源的充分回收造成严重的困难。因此,以先进的空区探测系统为手段,开展以空区精密探测为基础的相关技术的研究与应用,已经成为我国金属矿山安全生产所面临的重大前沿研究课题。综合运用理论分析、现场探测、地质建模等方法,以空区激光探测系统、矿业软件Surpac为主要工具,针对铜坑矿隐患资源回收具体工程实际,开展基于空区实测的复杂边界矿柱回采可视化技术的研究,获得了准确的矿柱三维模型及爆破设计参数,为有效回收隐患资源提供了重要的基础。
Large numbers of cavities formed by the underground mining of metal mineral resources not only endanger the mine safety but cause great difficulties in a full recovery of the resource. Therefore, it has become a major front research subject for the safety production in China＇s metal mines to take the advanced cavity detection system as the means to research and apply the relevant technology based on a precision detection of cavities. By a comprehensive application of theoretical analysis, site detection and geological modeling, with the cavity laser monitoring system and mining software Surpac as the main tools, in light of the reality of a specific project of recovering hidden danger resource in Tokeng Copper Mine, we carried out the research on the visualized technology for the extraction of the ore pillars at complex boundary based on cavity monitoring. As a result, an accurate 3 D pillar model and blasting design parameters were obtained, providing an important basis for an effective recovery of trouble resource.
