摘　　要：以狮凤山铜矿71#矿体940～965 m水平为研究对象,针对缓倾斜、倾斜的中厚难采矿体,经过分析、可行性论证,采用有底柱分阶梯回采方案进行试验。通过对难采矿体采用分阶梯回采的方案研究,在原分段的底部结构工程保持不变的前提条件下,根据矿体赋存条件、矿体开采技术条件,优化了采场结构参数。试验研究的结果表明,矿石贫化减少,采场生产能力增大,入选品位提高,运行成本降低,最大限度地回收利用了矿石资源。Based on 71 # ore-body in 940 - 965 m level in Shifengshan Copper Mine, the sub-level stoping method with sill pillars was adopted for the gently inclined to inclined and medium thick ore-body through the related analysis and feasibility demonstration. The sub-level mining of difficult-to-mine ore-body was carried out under the premise of the sill pillars structure remaining unchanged. The stope structure parameters were optimized according to the mining conditions and the occurrence of the ore-body. The test research results indicated that the ore dilution was decreased, the stope production capacity was increased, the processing grade was improved, the mining operation cost was reduced, and so that the mine resources were made full use of.
