MFFF is a specially designed fire suppressant that was created to fight intense fires in coal mines MFF uses a durable chemical composition that adheres to the fuel and resists heat for an extended period of time MFFF intensifies the penetration and wetting of preexisting water for greater fire suppression View All MFFF

Sep 21 2012 · Fire in an underground coal mine is hazardous because of the confined space possible effects on the ventilation system and limited and long evacuation routes Mine fires in conveyor belt entries can produce smoke and high levels of toxic gases that are carried throughout the mine by the mine ventilation system

fire fighting coal mill MFFF is a specially designed fire suppressant that was created to fight intense fires in coal mines MFF uses a durable chemical composition that adheres to the fuel and resists heat for an extended period of time MFFF intensifies the penetration and wetting of preexisting water for greater fire suppression

Fire protection requirements related to mining are extensive and differing since the industry is defined by large operations and complex production processes Fires and explosions pose a constant threat to miners and to the production capacity of mines A fire in a mine can have awful ramifications for human lives and economic viability

5 While fire and explosion risk assessments have to be carried out both below ground and on the surface this guidance relates primarily to fire and explosion risks below ground However the general principles should be applied to those buildings and equipment on the surface of a mine where a fire or explosion could prejudice safety below ground

Before fire suppression systems were introduced to and implemented in the mining industry in the 1960s there was a significant amount of crippling loss of equipment production and life due to

Explosion suppression is a variation of fire suppression Some European coal mines use this technology in the form of passive or triggered barriers on a limited basis Passive barriers consist of rows of large tubs containing water or rock dust that are suspended from the roof of a mine entry

fire suppression systems installed that may contain such agents The primary scheduled extinguishing agent used on mine sites is FM200 FE227 with some minimal use of NAF SIII and NAF PIII Halon systems halon 1301 halon 1211 have been phased out due to its significant ozone depleting
