| Abstract: | Based on geologic background of Shi Zuishan colliery, the single rock fracture seepage tests under the triaxial stressdo exists, the relations tests between the effective confining pressure and the fracture aperture. This paper revealed the single fracture gritstone seepage law in the three dimensional stress, and established the relationship among effective confining pressure, fracture pressure and coefficient of permeability, in order to enrich the seepage theory research on fractured rock mass. |
