Abstract
To improve the quality of high-moisture anthracite treated by hydraulic reservoir reconstruction technologies, the isothermal drying process of anthracite were studied experimentally. Based on the experiment results, after the fitting of thin layer drying model and the regression analysis, the prediction model was established. The results show that the isothermal drying process can be divided into the acceleration and deceleration stage. The effective water diffusivity increases with the increase of temperature and particle size. And the Page model fits the best. The prediction model is in good agreement with experimental data.
