Abstract

The invention provides a method for actively preventing sliding of a mine. The method includes the steps: firstly, arranging a plurality of pneumatically controlled locking claws on a rail of the mine at intervals; secondly, enabling a mine car to run along the rail through a winch; thirdly, acquiring the position and the running direction of the mine car through the winch. The locking claws are in a horizontal state allowing the mine car to pass in ventilation and are in a raising anti-sliding state forbidding the mine car to pass in non-ventilation in the first step. The locking claws are in the horizontal state when the mine car reaches a preset distance in front of the locking claws, and the locking claws are in the raising anti-sliding state after the mine car passes the locking claws. Therefore, sliding accidents of the mine can be safely and effectively avoided.

Description

technical field [0001] The invention relates to a safety method in a mine, in particular to a method for actively preventing a mine sports car. Background technique [0002] In the underground mining work of coal mines, sports car accidents may occur due to equipment defects or improper manual operation. Sports car accidents are the most frequent accidents in mines. The sports car mainly refers to the phenomenon that the mine car breaks away from the mechanical traction device, such as the traction of the winch or the hoist, breaks away from the running rail under the action of its own weight, and rushes into the mine. The hazards of a sports car accident are quite serious. In addition to damaging facilities such as cables, air pipes, and water pipes along the well shaft and along the lane, it will also injure or kill the operating personnel, resulting in personal injury and death accidents. [0003] The method that avoids sports car accident to take place in the prior art...
