盲竖井不停产原位延深关键技术研究

Research on Key Technology of In-situ Deepening of InteriorShafts without Production Stoppage

山东某金矿28线盲竖井在最大限度保障上部中段不停产的情况下,摒弃措施井工程,利用人工保护盘成功在原位进行竖井延深,取得了显著效益和效果,既满足了现阶段生产需要,又实现了增加后续生产接续的能力,为竖井延深提供了一条可借鉴的经验。

For the interior shaft of the 28 th line in a gold mine in Shandong Province,while ensuring that the upper and middle levels are not shut down to the greatest extent possible,the service shaft work is abandoned and the protective bulkhead is successfully used to deepen the vertical shaft in situ,achieving significant benefits and effects.This not only meets the current production needs,but also increases the ability of subsequent production continuity,providing a valuable experience for vertical shaft deepening.
