| 摘 要： | 本文通过实验室物理模拟试验和现场工业试验，详细研究了急倾斜中厚矿体在下盘围岩不稳定的条件下，沿走向布置回采进路的无底柱分段崩落法。优化了采场的结构参数，通过出矿前扩大回采进路的断面，保证了出矿进路靠近下盘布置，增加了崩落矿石的流动范围，减少了下盘残留，提高了矿石回收率。

| Abstract: | Through physical simulated tests and industrial field tests,this paper studies sublevel caving of the arrangement of mining entrance along the run of the ore vein and optimize the structure parameter in the stope.By enlarging the cross section of mining entrance before ore removal,the entrance of ore removal is enabled to be close to footwall arrangement,the scope of the flow of ore is made greater,footwall residual amount is reduced and the rate of withdrawal is raised. |

| Keywords: | High-dipping middle-thickness ore body Sublevel caving Physical simulation Rate of ore withdrawal |
