Coal Seam 14.5 of Khe Cham Coal Company - TKV has high self-ignition properties and the phenomenon of annealing and CO gas emission has occurred. One of the applied and effective solutions to help control the risk of endogenous fire during the exploitation of longwall kilns 14.5 is: Measuring and controlling the temperature, taking gas samples in the longwall fire burning area to Analyze and determine the content of gases in the longwall fire area.
