Abstract
The utility model discloses equipment for comprehensively preventing 'one-ventilation and three-prevention' accidents on a driving face. The equipment is arranged in an air return roadway of the driving face in a range of 30 to 50m away from the driving face and is used for preventing fire hazard, flood hazard, coal and gas outburst and other accidents on the driving face. The equipment is characterized in that: heavy supports are firmly fixed with four walls of the roadway into a whole; the heavy supports are firmly fixed with four walls of the roadway into a whole through anchor bolts and anchor cables; two sets of heavy steel air doors are arranged on the front and rear parts of the heavy support roadway on the four walls of the roadway and are firmly connected with the heavy supports into a whole; emergency exits are formed on the heavy steel air doors; an opening direction of each emergency exit is opposite to an opening direction of each heavy steel air door; the two sets of front and rear heavy steel air doors are controlled by a motor; and the motor is controlled by a high-temperature flue gas sensor. When a fire accident occurs on the driving face, high temperature or flue gas acts on the high-temperature flue gas sensor, the motor is controlled by the high-temperature flue gas sensor, and the heavy steel air doors are rapidly closed through the motor.
