中文摘要: 房柱法是缓倾斜薄矿体开采的主要方法之一,而房柱法矿柱回采是国内外均面临的重大技术难题。本文以南温河钨矿为工程背景,先采用理论计算人工假柱尺寸,然后就矿柱回采工艺及预期经济效益预算进行了研究。研究表明:1)人工假柱跨度平均为11 m,尺寸不小于4.35 m,人工假柱养护龄期不得少于20 d;2)试验采场内预计回收矿柱矿石量3 895.417 t,矿柱直接经济价值为495.37万元,利润311.92万元。通过试验阶段矿柱回采,能够为南温河钨矿今后矿柱回采大范围推广奠定坚实的基础,也为今后类似矿山矿柱回采提供了宝贵的借鉴意义。
Abstract:Room and pillar mining method is one of the main methods for the gently inclined thin ore bodies, and the pillar recovery in pillars mining process is a major technical problem at domestic and abroad. Taking Nanwenhe tungsten mine as engineering background, the size of the artificial concrete pillar (ACP) was calculated by theoretical calculation, and then the mining process and expected economic benefit budget were studied. The research indicated that: (1) the span of ACP were 11 m and the size of ACP was not less than 4.35 m, the curing age of ACP was not less than 20d; (2) the estimated ore recovery ore quantity was 3 895.417 t in the trial stope, and the economic values of pillar in trial stope was ¥ 4,953,700 and the profit was ¥ 3,109,200. Through the mining process of the pillars in the trial stage, it can lay a solid foundation for the large-scale promotion of the pillars of the Nanwenhe tungsten mine, and also provide valuable reference for similar mining pillars in the future.
