Research on Key Technology of In-situ Deepening of Interior Shafts without Production Stoppage
For the interior shaft of the 28thline 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.
