【 摘 要 】

Fly ash cemented fire-prevention materials are mainly composed of curing agent, fly ash filling aggregate and other additives. The fire-prevention material has the characteristics of expansibility and adjustable solidification time, strong support ability and low economic cost, which is suitable for leaking stoppage and preventing fire in coal mine. Through the experimental study, the strength and rheological properties of the material are analyzed, and the mechanical parameters of the fly ash cemented fire-prevention filling materials are obtained. The correct and reasonable use of this fire-prevention filling technology will lay a good foundation for the wide extension of the fire prevention and extinguishing technology.
