Abstract

Coal seam heat injection is a new way of strengthening drainage gas. In the thermal process in coal seam, steam humidity increases will affect the extraction of coal seam gas. In order to grasp the effect of humidity on the steam injection thermal process, on the basis of previous research and heat transfer, fluid mechanics, theory of elasticity, adding the effects of humidity, the thermal coal injection multi-physics coupling model with humidity effects is established. The model is helpful for future numerical analysis and related laboratory experiments.
