the fracture as a very important permeability channel is taken into account in the theoretical research on percolation of medium
the research methods of percolation in 3D porous and fractured double-medium is put forward
and the percolation model of 3D porous and fractured double-medium are established. The model applies to more fields
such as coal bed
rock mass. Based on VC++6.0
the software of 3D is developed
the percolation and the percolation law of 3D porous and fractured double-medium are simulated. The results indicate that fracture in the model increases the value of percolation probability observably. It makes the percolation law of double-medium differ from the law of porous medium. The natural phenomena of percolation transition happens surely with the increase in porosity
fracture fractal dimension and fracture number distribution initial value.
