Abstract: We analyzed the spontaneous combustion prevention technology by MEA colloid material for the greater concealment and danger characteristic of coal roadway with high caved point spontaneous combustion. The high caved point spontaneous combustion status monitoring was realized by artificial intubation and beam tube monitoring tests facility. We introduce the fire prevention and control mechanism and construction technology of MEA colloid material, and select MEA material for high caved point fire prevention and control. The partial high caved points was plugged and spouted by MEA material in typical coal mines. The MEA material played a good effect to prevent and control high caved point spontaneous combustion by analyzing the temperature variation tendency of three high caved points.
