Background
With the rapid development of coal mine enterprises and the large-scale mechanized investment, the scale of mines is larger and larger, but the occurrence probability of mine fires is increased at the same time, so that the life safety of miners is threatened. At present, although some fire fighting equipment exists, the best fire fighting time is delayed from the processes of preparing equipment, connecting a power supply and the like, and because the electric equipment is used, in addition, the preparation cabin is promoted to bury hidden dangers if the explosion is lost during fire fighting, other accidents are caused, and the fire fighting work is influenced. These are disadvantageous to safety.
Mine fires, whether occurring on the ground or underground, threaten mine safety production and life safety of operating personnel, and after the mine fires, the fire is rapidly developed and is difficult to control, the influence range is wide, gas and coal dust explosion accidents can be caused more seriously, and property loss and life safety of the operating personnel cannot be guaranteed due to serious accidents. In addition, due to the complexity of fire, it is generally very difficult to rescue, especially due to the outburst, uncontrollable and violent fire in the mine, so besides enhancing the prevention, it is also necessary to extinguish the fire as soon as possible in case of fire to eliminate the fire in the bud. The electric high-foam fire extinguisher comprises the following steps from preparation to foaming: the organization personnel, prepare the apparatus, connect the power supply, etc. process, and need four to five persons' cooperative operation at least, these will certainly delay the best opportunity of putting out a fire, and because the electrical equipment that uses, what the preparation storehouse promoted when putting out a fire again because of the unfavorable operation or improper installation exists the explosion will bury the hidden danger again, these are all unfavorable for the safety.
