摘　　要：对薄和中厚矿体岩金开采所开展采矿方法综合试验研究,采用人工底柱浅眼留矿法所存在的独立采空区与其揭露的钢筋混凝土人工底柱,进行稳定性分析研究,以便对这类采空区的独立存在与人工底柱的施工质量进行评价,为矿山以后做到安全生产、缩短工程时间、减少材料消耗、增加企业效益提供帮助。A comprehensive test on the mining method for thin and medium thick gold rock deposit was carried out. Stability analysis was made on an independent mined-out area by short-hole shrinkage stoping with artificial pillars and its reinforced concrete artificial pillars so as to evaluate their engineering quality, which aimed to provide an assistance to increasing the enterprise benefits by safe production, shortening the engineering period and reducing material consumption.

关 键 词：浅眼留矿法 独立采空区 钢筋混凝土人工底柱稳定性 分析研究
