| 摘 要： | 分段中深孔落矿留矿法在急倾斜中厚矿体中应用广泛。广西大新锰矿部份矿体为急倾斜中厚矿体。介绍在设计时注重考虑采矿方法、矿柱回采、采空区处理之间的关系,选择合理回采顺序,以及矿柱回采和处理采空区方法。结合矸石充填采空区的处理方法,达到稳定地压,消除采空区隐患的目的。

| Abstract: | A wide application is found in subsection of medium-length hole of ore method in sharp inclined medium thick ore-body.Daxin Manganese Mine with its ore is a partial sharp-inclined or thick ore-body.This paper will introduce the designment attention to the mining method,including the recovery of mine props and the relationship.Combined with dead zones of waste rock,we try to use the disposal method to achieve stable pressure,only to eliminate hidden dangers of mined-out. |

| Keywords: | Segmentation or deep blast hole Recovery of mine props Fill the dead zones in mining |
