%X On the basis of an experimental study, a permeability law of natural fracture under 3D stresses is developed. The relations between fracture closure b and permeability coefficient kf, equivalent normal stress ne and b are also formed. Compared to the modified cub law, the permeability law is proved reasonability. The change of permeability characteristics under high stresses is discussed primarily.
