Ore bin is an important channel for ore sliding conveyance, it is often damaged by ore impact, which severely affect the normal production of the mine. On the basis of ore movement trajectory and energy conversion and conservation principle, detailed analysis is conducted for the damage mechanism of ore bin wall. Aiming at the repair conditions of the transfer ore bin of a certain mine in China, four feasible technical options for reinforcement are put forward, detailed analysis is made for the pros and cons of various technical options, and the lateral comparison is conducted for the affecting extent of various factors. The optimal option fitting the mine actual conditions is obtained and applied to the practical use. The application results show that using this technical option can remarkably reduce the phenomenon of broken damage of ore bin wall so that the goal of protecting ore bin is achieved and the safe production of the mine is realized, which has a certain practical significance and engineering value for improving the buffer design of the ore bin of the mine and the production management.
