The invention discloses an electric hoist used for a mine. The electric hoist structurally comprises a lifting hook, a pull rope, a winding drum, a shell, a moving structure and a motor. The winding drum is installed in the shell, the pull rope is wound on the winding drum, the bottom of the pull rope is connected with the lifting hook, the motor is installed on the side face of the shell and connected with the winding drum, the moving structure is connected to the top of the shell, and a brake structure is arranged in the motor. The brake structure comprises a brake disc, a brake ring, a brake seat and a spring, the brake disc is arranged on the side face of the brake seat, the brake ring is arranged on the inner side of the brake disc and cooperates with the brake seat, and the spring is connected between the brake seat and the brake disc. The electric hoist has the beneficial effects that a friction rod achieving outward jacking during braking can compensate the worn brake ring, brake force is prevented from being reduced, and the shutdown gliding distance is prevented from exceeding the specified requirement.
