摘　　要：根据地下残矿开采形态复杂、安全条件差的特点,对比各种采矿方法优缺点,研究提出利用采空区为补偿空间的区域整体爆破嗣后充填采矿方法。将残矿周围采空区作为爆破补偿空间,利用大直径深孔一次爆破落矿,集中出矿后对采空区进行大流量充填。该技术在残矿开采中取得了良好的应用效果。According to the features such as complex forms and poor safety condition of the mining of underground residual ore, and comparing the advantages and disadvantages of various mining methods, it is recommended to adopt the cut and fill mining method through taking the mined-out area as the regional blasting relief space. The study suggests taking the surrounding mined-out area as the regional blasting relief space, conducting one-time blasting with the large-diameter longhole, and carrying out the largeflow filling after concentrated ore removing. This technology has obtained good application effect in residual ore mining.
