An experimental study on permeability characteristics of coal with slippage and temperature effects

Ground temperature rises with the increase of mining depth. In this study, in order to investigate the seepage properties of coal with slippage and temperature effects, a thermo-fluid-solid coupling experiment on the methane-bearing coal was performed via the triaxial servo-controlled seepage equipment. Then, the permeability of coal in the gas loading-unloading processes was measured under different temperatures. Finally, a fractal slippage...
