Ruilong Mine shaft lifting capacity does not meet the design requirements of the mine. The lifting system contradicts to the mine production prominently. Besides, due to defects in design and installation and other factors during the construction of the main shaft, there are many security risks in the enhance system. After the efficiency optimization, the accident rate of the lifting process greatly reduced, the limiting production time is greatly shortened, the security risks are completely eliminated, the bottleneck of the production of the mine is effectively alleviated, which provides more flexible space for production arrangement.
