The invention relates to the technical field of mine hoist corollary equipment, in particular to an accidental falling speed reduction structure for a mine hoist, which comprises four supporting columns distributed around a mine wellhead, a mounting frame body is fixedly mounted among the four supporting columns, a rope containing roller driven by a motor is arranged in the mounting frame body, and a rope containing groove is formed in the rope containing roller. One end of the rope containing roller is provided with a speed measuring assembly exposed out of the installation frame body, a sensing cover body is arranged on the side, close to the speed measuring assembly, of the installation frame body, a vibration sensor is arranged on the sensing cover body, and the other end of the rope containing roller is provided with a buffering brake device located on the inner side of the installation frame body. An electric telescopic rod used for controlling whether the rope containing roller rotates or not is arranged between the mounting frame body and the buffer braking device, and a preparation driving structure located in the mounting frame body is arranged on one side of the buffer braking device. According to the accidental falling speed reduction structure for the mine hoist, accidental out-of-control of the rope containing roller can be effectively monitored, the anti-falling effect is achieved through flexible speed reduction, and secondary damage caused by accidents is avoided.
