| 摘 要： | 矿柱回收顺序的选取对采空区处理过程中围岩的稳定性、安全性具有重大意义，矿柱回收顺序成为采空区处理课题研究的首要问题。采用FLAC3D，对东升庙铅锌矿2#采空区矿柱从一端到另一端顺序回采、从两端到中央推进回采、间隔跳采、从中央到两端推进这4种矿柱回收方法进行数值模拟，通过对比分析研究表明，比较合理的矿柱回收顺序为从中央向两端推进，可为安全生产提供保障。

| Abstract: | How to arrange the sequence of pillar recovery is of great significance to keep the stability and safety of surrounding rocks in mined-out processing. The sequence becomes the key issue to study the goaf treatment. FLAC3D numerical simulation is adopted to simulate four kinds of pillars'' recovery at No.2 goaf in Dongshenmiao lead-zinc deposit, that is, from one end to the other, from two ends to the middle, interval mining, and from the middle to both ends. Through contrasting and analyzing, a more rational recovery sequence of from the middle to both ends is obtained, which can guarantee the production safety. |
