摘要
介绍了红透山铜矿在超千米深度下用两步骤采矿方法减少矿柱损失，控制地压活动，保证生产安全并获得良好技经指标的做法；探讨了与之相关的充填体支护矿柱机理、块石胶结充填体自立、爆破对充填体稳定性的影响、留矿法在深井采矿中的应用、中深孔布孔参数等相关理论与应用。
This paper introduces the two-stage mining in depth of over a thousand meters in HongtoushanCopper Mihe to reduce the pillar loss, control the ground pressure activity, ensure the production safety, andachieve the good techno-economic indexes; dissusses the related theories and applicatiop such as: the mechanismof supporting the pillars with filled mass; the independence of lumpy rock-cement filled mass; effects of blastingon filled body; application of shrinkage stoping in deep mining; middle-deep hole pattern parameters and so on.
