[0002] The mine hoisting system is an important part in the process of mine production. Among them, the frequency of runaway accidents in the inclined shaft track hoisting system during operation is relatively high. The most harmful accident in the mine inclined shaft track transportation is the runaway accident. The inclined shaft track runaway accident mainly refers to the situation where the vehicle breaks away from the mechanical traction device (winch, hoist) on the slope and rushes into the mine under the action of its own gravity. The harm of the derailment runaway accident is quite serious. In addition to damaging facilities such as the shaft and cables, air ducts, and water pipes along the roadway, it will also injure or kill operating personnel, causing personal injury and death accidents.
