Direct determination of the diffusion coefficient variation of coal based on Fick's law and model establishment

Direct determination of the diffusion coefficient variation of coal based on Fick's law and model establishment

Gas diffusion ability directly affects gas exploitation, outburst risk, emission and content determination. In order to study the influence of stress, gas pressure and temperature on gas diffusion coefficient in coal, the gas diffusion coefficient in columnar coal sample was measured with stable con...
