Research on Influence of Coal Adsorption Properties upon Its Gas Diffusion Characteristics

Abstract：AdsorPtion ProPerties rePresent the gas storage Performance of coal and diffusion characteristics of coal show the gas release ability of coal,and both are the necessary conditions leading to coal and gas outburst. In order to find out the inner relationshiP between the absorPtion ProPerties and gas diffusion characteristics of coal,exPerimental research was carried out on the change regularity of gas diffusion characteristics of coal with different gas adsorPtion ProPerties by combining with the existing exPeriment conditions and taking the relationshiP between the limit gas adsorPtion amount of coal samPle and the initial gas diffusion velocity of coal as the breakthrough Point. The exPerimental results showed that the initial gas diffusion velocityΔP of coal increased with the increase of coal adsorPtion constants a,and a linear relationshiP existed between them.
