As the engineering constructing such as CBM (Coalbed Methane) mining,oil-gas field development, groundwater remediation and underground nuclear wastestreatment, seepage characters of water-air two-phase flow in fractured rock mass havean more and more attention.
Using experimental test, theoretical analysis and numerical simulation, this paperstudies the characteristics of pressure, water-air flow rate, the impact of water-air flowratio on water-air relative permeability. And some research results are g...
