| Abstract: | In this paper,breaking through the traditional research path of flow theory from macroscopic view to macroscopic view,the complex flow process of mash gas desorption,diffusion and seepage in coal seam is studied by using Monte Carlo simulation and molecular simulation.The process of mash gas adsorption and desorpton is discussed based on Monte Carlo simulation,and the process of mash gas diffusion and seepage is discussed based on molecular simulation.The emphases and difficulties in studying the flow law o... |
