Once an open fire has occurred in the chamber, the site personnel should use the fire-fighting equipment around them to try to extinguish the fire (electrical fire first), and report to the mine dispatching room in time. When the explosive material library is on fire, the detonator should be shipped out and the explosives should be shipped out. If the heat is not available, close the fire door and return to a safe place. When the winch room is on fire, the mine car below the fire source should be fixed, or the mine car should be placed in the lower yard to prevent the car rope from being burned and causing the sports car to hurt people. When the battery garage is on fire, in order to prevent hydrogen explosion, the power should be cut off, charging should be stopped, ventilation should be strengthened, and the battery should be transported out of the chamber in time. If there is a fire in the diverticulum, the fire door should be closed immediately. When there is no fire door, the wind barrier should be used to control the wind and actively extinguish the fire. When the fire chamber is located in the main inlet duct of the mine, it should be anti-wind or short-circuit the fire smoke. When it is located in the intake duct of the mining area, short-circuit ventilation or partial wind reversal may be adopted if the conditions are met.
