Based on percolation theory of porous medium, the fracture as a very important permeability channel is taken into account in the theoretical research on percolation of medium. The research method on percolation of more general porous and fractured double-medium is put forward. Through the numerical calculation on the pore and fracture in donc in 2D, the relation between percolation probability and important parameters such as porosity, fracture fractal dimension and initial value of fracture distribution are obtained. The mathematical formula on percolation threshold of porous and fractured double-medium is also obtained. The percolation law of pore and fracture is further shown.
