Preparation and application ofadsorption-desorption-seepage experimental device for loaded coal containing gas

摘要：

　　This paper introduces the experimental functions and application of an adsorption-desorption-seepage experimental device for loaded coal containing gas.The experimental device is composed of loading system, axial pressure vessel, pore pressure control system, temperature control system, data acquisition system and auxiliary system; its maximum axial pressure is150MPa, maximum confining pressure is 40MPa and highest heating stable temperature is 100℃.The experimental is capable of accurately simulating the formation environment in which the actual coal seam gas seepage is located.An experimental seepage study has been carried out used by the experimental device, in which the gas adsorption and desorption roles on the loaded coal containing gas under different loading conditions are considered.The results show that confining pressure, gas pressure,temperature and effective stress have important effects on the permeability of loaded coal containing gas.
