Experimental Study on Influencing Factors of Coal Permeability
Abstract：Permeability testing has been completed by triaxial experimental device at different confining pressure,different gas pressure and different temperature.The laws of these factors affecting on permeability have been got.The results showed that： permeability increasing gradually with the confining pressure decreasing;permeability decreasing but gas flow increasing with the adsorption pressure improving;the effect of temperature is smaller compare to the other two factors.
