In this paper, the solvent swelling processes of coal particles of Zao Zhuang coal, PDC-HV coal, and Witbank coal were simulated using a new model, which has the natures of the second-order system with the denominator τ^2s^2+2ζτs+1 and a unit-step forcing function (1/s). The simulated results of Zao Zhuang coal particles using the new model agree very well with measured ones by OMIA (orthogonal microscopy image analysis) technique proposed by us. This suggests that the overshoot swelling of coal particles in some coals can be interpreted by the second-order system.
