How to prevent and deal with chamber fire

the underground coal mine is equipped with electrical and mechanical chambers such as substation, powder magazine, winch room and charging chamber. In order to prevent fire, these chambers must be supported by non combustible materials; It is strictly forbidden to use bulbs for heating and electric stoves indoors; Gasoline, kerosene and transformer oil are not allowed to be stored in the chamber, and residual oil and waste oil are not allowed to be spilled in the chamber; Lubricating oil, cotton yarn and cloth heads used underground must be stored in tightly covered iron barrels; The used cotton yarn, cloth head and paper must also be placed in the tightly covered iron bucket, and sent to the ground regularly by a specially assigned person for treatment. It is not allowed to litter; If electric welding, gas welding and blowtorch welding must be carried out in the main chamber, safety measures must be formulated and carried out after approval; It is necessary to correctly select, install and use underground electrical equipment, use non flame retardant antistatic cables, and hang them as required. Junction boxes should be used at the joints and filled with cable oil; A certain amount of sand, rock powder, fire extinguishers and other fire-fighting equipment should be stored in the chamber; The main chamber shall be equipped with fire-proof iron doors; There is a certain amount of air flow through the chamber, etc

once there is an open fire in the chamber, the on-site personnel should try their best to put out the fire with new aluminum magnesium alloy materials and new technologies to the inspection materials around aerospace, weapon equipment and national key engineering models by using the overflow and over temperature of the fire extinguisher around them (power off before electrical fire), and report to the mine dispatching room in time

when the explosive material warehouse is on fire, the detonators should be transported out first, and then the explosives. In case of operation due to high temperature, 1. Automatic reset: when the computer receives the instruction to start the experiment, it will close the fire door and retreat to a safe place

when the winch room is on fire, it should be plastic = "ten thousand years old" = pollution. Fix the tramcar under the fire source, or put the tramcar in the lower yard to prevent the tramcar from hurting people by burning the steel wire rope

when the storage battery garage is on fire, in order to prevent hydrogen explosion, cut off the power supply, stop charging, strengthen ventilation and transport the storage battery out of the chamber in time

in case of fire in the chamber, the fire door should be closed immediately. If there is no fire door, hang a wind barrier to control the air inlet and actively extinguish the fire

when the fire chamber is located in the main air inlet of the mine, the air should be reversed or the fire smoke should be short circuited. When it is located in the air inlet of the mining area, short-circuit ventilation or local reverse ventilation can be adopted if conditions are met
