What kind of fire should be handled when the whole mine is against the wind?

When dealing with the wellhead, shaft and bottom of the intake shaft, the whole mine should be ventilated to prevent fire.

Article 89 When anyone discovers an underground fire, he shall, according to the nature of the fire, the ventilation and gas situation in the disaster area, immediately take all possible methods to put out the fire directly, control the fire, and report to the mine dispatching room quickly.

In the process of rescue and fire fighting, it is necessary to designate a special person to check the changes of concentration, wind direction and air volume of harmful gases such as methane, carbon monoxide and coal dust, and take safety measures to prevent gas and coal dust explosion and personnel poisoning.

Article 93 When dealing with external mine fires in different places, the following provisions shall be met:

First of all, when dealing with fires on the mountain and under the mountain, measures must be taken to prevent airflow reversal caused by fire wind pressure and airflow blockage caused by roadway collapse.

Before going against the wind, people on the windward side of the fire source must be evacuated and measures should be taken to prevent the fire from spreading.

When several main ventilators jointly ventilate the mine, it is necessary to ensure that the main ventilators in the non-accident area are against the wind first, and the main ventilators in the accident area are against the wind later. When taking short-circuit measures, all personnel in the affected area must be evacuated.

Three, when dealing with the fire in tunneling faces, the original ventilation state should be maintained, and measures should be taken after reconnaissance.
