Abstract：Through monitoring the O 2 , CO 2 and CO content changes under simulated conditions and the spontaneous combustion analysis on coal shipping, and combining with practical production, the spontaneous combustion prevention research were done for high temperature coal, old coal and raining-wet coal of Shenhua, it was shown that: fuel cabin and engine cabin which could heat the coal in neighbor cabins would improve the slow oxidation rate, so the cabins which were near the fuel cabin and engine cabin should be the emphasis of spontaneous combustion prevention; the high temperature coal and old coal shipping was better to be forbidden, after rain, the existing of high temperature point could lead to spontaneous combustion; making the cabin hermetic was the ideal method to prevent the spontaneous combustion of shipping coal.
