| Abstract: | As an important means of predicting and forecasting coal spontaneous combustion，iconic gas has been widely used，and the key to its technology lies in the selection of iconic gas.The coal sample from the 1313 working face of Weiqiang Coal Mine was selected to carry out the temperature-programmed laboratory experiment to analyze the relationship between gas products and temperature during the natural oxidation process of coal，and to determine the symbolic gas and auxiliary indicators of natural combustion in Weiqiang Coal Mine.The research results had certain guiding significance for the fire prevention and fire prevention in the goaf of Weiqiang Coal Mine. |
