By maximum water of experimental study on moisture absorption characteristics of low rank coal in Ordos after drying, the absorption after drying coal in the natural environment was determined. Results showed that for the coal, most economical moisture content was about 12% after drying coal. The characteristics of coal spontaneous combus- tion was studied by experiment, and the results showed that the coal spontaneous combustion in transportation and storage can be effectively prevented by taking reasonable measures.
