Influence of Fractal Distribution of Rock Joints on the Permeability Behavior of Methane Transform

摘要：

Estimation of methane permeability in jointed rock mass is important to provide input parameters for numerical models simulating transient methane flow. The influence of fractal distribution of rock joints on the permeability behavior of methane transform is presented by using fractal geometry and Darcys law. The self-similar property of fracture network is applied to quantitatively describe the fractal distribution of rock joints. Based on the parallel theory of network and Darcys law, the effective permeability of jointed rock mass is proposed.
