The boring work surface is generally not equipped with fresh air by the ventilator installed on the ground. In order to make the boring work surface have enough fresh air for the staff to breathe, dilute and eliminate the gun smoke, dilute and eliminate toxic and harmful gases, Heat and water vapor, etc., install a local fan in the roadway at a certain distance from the heading face, and connect the air duct to the air outlet of the local fan to send the wind to the heading face. The local ventilator is responsible for the important task of supplying air to the heading face all day and night. Therefore, each local ventilator must be managed by the designated personnel, and the following management system should be strictly implemented.

1. It is necessary to ensure that the local ventilator is always in operation. No matter whether the boring working face is normally produced or handed over, it is not allowed to stop the wind at will, and it is necessary to ensure sufficient air volume for the boring working face.

2. When the wind is stopped due to maintenance or power failure, the personnel must be evacuated to cut off the power supply of all equipment in the working face. Therefore, the local ventilator and the electrical equipment in the heading face must be equipped with wind power locking devices.

3. Before the ventilation is restored, it is not allowed to send electricity and enter the work. Before the ventilation is restored, the gas must be inspected. If the gas concentration in the airflow within 10 meters near the local ventilation machine and the switch site does not exceed 0.5%, the local fan can be manually activated. .

4. Press-in local ventilator and starting device must be installed in the air inlet roadway, and the air return port should not be less than 10 meters to avoid circulating wind.

5. The start or stop of the local ventilator must be handled by a special person. Other personnel are not allowed to start or stop the local ventilator without permission.

6. The air duct must be hung on the side of the roadway. In the roadway, the shed, the cart, and the material handling equipment should not be damaged. When the gun is fired, the air duct cannot be broken. The air cylinder should be hung, straightened, and sturdy. The corner should be gentle. Do not wrinkle the air duct. Use the same specifications of the air duct.

7. After the local ventilator is started, the blades will rotate very fast. Do not put your hands in, or stuff the wooden sticks and other things into it.

8. If the same tube is found to be broken, report the ventilation personnel immediately so that it can be repaired immediately to avoid air leakage and affect the ventilation of the driving face. Everyone in the well should take care of the local ventilator and the same cylinder, because it is the health, personal safety and safe production of the boring face and related personnel, so everyone should pay attention to the operation of the local ventilator and find abnormal conditions. Immediately report the ventilator or mine dispatch room for immediate disposal.
