Fractal Characterization of Pressure-Relief Gas Permeability Evolution in a Mining Fracture Network

Fractal Characterization of Pressure-Relief Gas Permeability Evolution in a Mining Fracture Network

The process of underground coal mining fractures the overlying strata and may provide storage and transportation space for gas by changing the roof rock permeability, which is released by pressure after mining. This paper adopts the experimental method of physical similarity simulation and combines...
