Three equations to estimate the permeability coefficient of fracture system in rock mass are presented. These equations are obtained from theoretical consideration of flow behaviors in a fracture with rough walls and elaborate measuring of some features in actural rock mass such as the as the roughness of fracture wall, distribution of fracture width and the average spacing width. These equations can also be used to calculate the permeability tensor of rock masses.
