Abstract：In order to predict the spontaneous combustion in the No. 3 coal seam of Chahasu coal mine, 5 coal samples were selected from the coal seam and the effect of temperature rising programmed test on process of coal oxidation was studied. The rules of gases emissions such as CO, C2 H4 under different temperature were analyzed and the indicator gases were selected according to the test results. The grading pre - warning index of carbon monoxide was determined according to the actual conditions of Chahasu coal mine.
