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660 m中段676 m分段至684 m分段14~20勘探线之间,工业储量22 778 t,实验取得的采矿损失率与贫化率分别为23.65%和18.18%。

Abstract: The experimental investigation of the pillarless sublevel caving mining method is introduced in detail in Nalin 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.
