Experimental Study on Permeability of Coal during the Complete Stress-Strain Process with Different Gases

Wang Chen1,2,Xian Xuefu1,2,Zhou Junping1,2,Gu Dasheng1,2 (1.State Key Laboratory of Coal Mine Disaster Dynamics and Control,Chongqing University,Chongqing 400030 2.College of Resource and Environment Science,Chongqing University,Chongqing 400030,China)  
The permeability research of coal during the complete stress-strain process is carried out on the 3-axis servo seepage device using adsorptive gas(CH4,CO2) and non-adsorptive gas(He) as the seepage medium.The test result shows that the seepage rate-strain curves of three kinds of gas are close to each other.Comparatively,the relative stress-strain curve changed slowly,especially for the adsorptive gas.Up to yield point in the elastic stage and at the strain softening stage,permeability and effective stress have a negative exponential relationship.For different adsorptive gas the coal seepage rate is different.In case of coal sample saturated with adsorptive gases,it is found that the seepage rate of CO2 and CH4 is decreased by 55% in average and the seepage rate of CO2 is less than that of CH4.
