摘　　要：详细介绍了无底柱分段崩落采矿法在那林金矿实验研究的情况。根据矿体的赋存特征，采用无底柱分段崩落采矿法开采该矿的倾斜中厚矿体，经过一段时间的应用与实践，取得了较好的经济效益。实验采场选择在660m中段676m分段至684m分段14～20勘探线之间，工业储量22778t，实验取得的采矿损失率与贫化率分别为23．65％和18．18％。The experimental investigation of the pillarless sublevel caving mining method is introduced in detail in Na- lin Gold Mine. According to the occurrence features of ore-body, the pillarless sublevel caving mining method was adopted to explore the inclined medium thick ore-body. Good economic benefits were obtained after application and practice for a period of time. It chose the sublevel of 676 m -684 m within the middle section of 660 m and the exploration lines between 14 and 20 as the experimental stope with industrial reserves of 22 778 t. In experiments, the mining loss and dilution rates were 23.65% and 18. 18% respectively.
