Adsorption Role Affected to Gas Permeable Law of Coal Mass
Abstract：A self developed gas permeability test device was applied to study the adsorption role affected to the gas permeability of the gas seam from the adsorption pressure, adsorption pressure difference and adsorption temperature, meanwhile, simulated and analyzed the var-iation law of the permeability with gas drainage. The results showed that the adsorption value of the same coal samples would increase and the permeability would reduce with the adsorption pressure increased. Under the same adsorption pressure, with the adsorption tempera-ture increased, the permeability would reduce. After the seam gas drained, the gas pressure would reduce, the permeability improved, it was the same to the experiment law.
