Abstract: The present disclosure discloses a method for collaboratively controlling a multi-channel braking system of a mine hoist, including obtaining the abrasion loss of the brake shoe by detecting position information of the brake shoe of each of disc brakes in real time, dividing abrasion loss levels by determining different abrasion degrees of the brake shoe, formulating three braking force distributing modes: an average distribution, a proportional distribution, and an index distribution according to the abrasion loss levels, thereby dynamically adjusting a set braking pressure of each of the disc brakes, tracking and controlling the set braking pressure through the disc brakes by adopting a pressure closed-loop control method by utilizing a pressure signal feedback from an oil pressure sensor, implementing a collaborative braking control of the multi-channel braking system of the mine hoist based on the abrasion loss of the brake shoe.
