An anti-falling brake-buffer system for a mining express elevator comprises brake ropes fixed at the two sides of a car platform sill, one end of each brake rope is fixed at the top of a vertical shaft, the other end of the brake rope is fixed at the bottom of the vertical shaft, and a linkage mechanism is arranged at the bottom of the car platform sill, a buffer is arranged at the top of the brake rope, a tension connector is arranged at the bottom of the brake rope, and a safety tongs of the brake rope, which is fixed on the brake rope and connected with the linkage mechanism, is arranged at the bottom of the car platform sill; and the buffer comprises a pair of inversed progressive safety tongs of the brake rope, a buffer rope connected with the brake rope is arranged in the progressive safety tongs of the brake rope, and a buffer rope clamp is arranged on the buffer rope. According to the anti-falling brake-buffer system for the mining express elevator, the installation is convenient, the buffer force of the brake rope is constant and adjustable, the anti-falling braking is reliable, and the safety of a non-rigid guide rail elevator in high-speed running is improved. The anti-falling brake-buffer system can be acted on the brake rope to play a buffer role, also plays a role of braking reliably when the elevator falls or brakes, so that the safety of the mining express elevator in the high-speed running can be improved.
