2017-9-1  The mechanism and advantage of inhibitive foam to prevent and control spontaneous combustion of coal are as follows: (1) the foam is very light and has large bulk, so it is easy to fill the whole fire area and to catch source of ignition and then to extinguish it automatically; (2) a large amount of water in foam moistens the heated coal, which can take away mass of heat, at the same time, the foam can cover and enclose the whole coal body to isolate the oxygen to extinguish the coal
