Overview of flame retardant mechanism of fire prevention and extinguishing materials for preventing and controlling spontaneous combustion in coal mines
Spontaneous combustion in coal mines is the most common and influential type of mine fire,which seriously restricts the safe mining of coal mines in China,endangers the safety of workers,and causes environmental pollution and great waste of resources.Al-though the prevention and control technology of mine fire has made significant development,the situation of preventing and controlling coal spontaneous combustion in mines is still severe.The influencing factors of coal spontaneous combustion in different mines or min-ing areas are numerous and complex,and different fire extinguishing materials and flame retardant mechanisms are used.This paper summarizes the flame retardant mechanism of mine fire prevention and extinguishing materials such as grouting,inert gas,inhibitor,gel,foam,etc.,and indicates the research direction of the flame retardant mechanism of mine fire prevention and extinguishing materi-als,which provides a reference for the research of fire prevention and extinguishing materials for preventing and controlling spontaneous combustion in coal mines.
