| 摘 要： | 金川二矿区采用多中段大面积连续回采工艺,水平矿柱开采稳定性是关系到二矿区乃至整个金川集团公司能否持续稳步发展的关键技术问题。采用FLAC三维有限元数值分析方法对此进行了研究,研究表明,在多中段回采过程中,水平矿柱的开采是个平稳回采过程,今后水平矿柱回采不会出现应力过大集中,也不可能出现水平矿柱灾变失稳。

| Abstract: | Jinchuan No.2 mine is using a multi-level large-area continuously mining technology.The mining stability of horizontal pillars is the key technology related to the persistent and steady development of the No.2 mine and whole Jinchuan Group Ltd.FLAC-3D numerical simulation is adopted in this study.The results show that the mining of horizontal pillars is a smooth recovery process in the period of multi-level mining,there is no high concentration of stress in the future mining of horizontal pillar,indicating that no catastrophic instability of the horizontal pillar will occur. |
