Abstract：During a mine shaft construction period ,although the hoisting protection device of the mine shaft was continuously improved ,a mine shaft cage falling accident was occurred sometimes. The small accident would damage the materials and equipment and large accident would cause casualty . After the cage falling accident occurred in the mine main shaft of Mengcun Mine ,with the calculation on the bra‐king torque of the mine hoister and analysis on the action principle of the anti-falling catcher ,the paper clearly pointed out that the braking oil pressure insufficient and the action inflexible of the catcher were the main causes of the accident occurred. The relevant prevention measures were provided on the actions ,coupling device ,dynamic braking and other aspects of the catcher.
