To improve the quality of anthracite disposed by fracturing technology, the dehydration characteristics of anthracite were studied experimentally. The influences of temperature and particle size were investigated. The results show that the drying temperature has significant effects on water loss rate. The higher the temperature is, the faster the growth rate decreases. The particle size has little effects on the water loss rate at the beginning of dehydration process. So compared with reducing the particle size, increasing the temperature can promote the dehydration of anthracite in initial stage. Smaller particle size benefits the dehydration process.
