Abstract
With the increase of the depth of shaft construction, shaft wall safety and the construction are becoming difficult. To ensure the safety and shaft wall construction safety and other factors, the real-time control and monitoring of the construction process is necessary. Feedback monitoring is an important method to ensure the construction safety. Base on the background of Benxi Dataigou Iron Mine's ultra-deep shaft with diameter of 6.5 m, depth of 1 640 m, the paper proposed methods to monitor the shaft wall safety and the condition of construction. It introduced the information construction for video monitor system, hanging plate important point monitor system and promoting bucket monitor system. The monitor system implementation plan may provide detailed information for ultradeep shaft efficient construction.
