摘要
以太白黄金矿矿柱回采及采空区处理为研究对象,通过FLAC^(3D)对矿柱回采稳定性进行数值模拟分析,研究矿柱回采顺序及回采方案,建立空区分布模型,通过技术经济分析和空区处理方案的数值模拟,确定了矿柱抽采的优化方案及采空区处理的安全措施,并在实际生产应用中成功回采矿柱矿石12.25万t,为矿山带来了较好的经济效益和社会效益。
Taking Taibai gold mine as a research object, the stability of pillar extraction was numerically simulated and analyzed by FLAC3D. The sequence and scheme of pillar ex- traction were studied, and the distribution model of goal was created. Through the technical and economic analysis, as well as the numerical simulation of goaf treatment, the opti- mization scheme of pillar extraction and safety measures of goal treatment were determined, and 0.1225 million tons of pillar ore was recovered in production, with good economic and social benefit.
