Experimental Investigation of the Fractal-Permeability Properties of Locally Fractured Coal Bodies around Gas Extraction Boreholes
To investigate the permeability characteristics in the in-situ fractured coal body around the perimeter of gas extraction boreholes, the steady-state permeability of fractured coal bodies with different gradations was tested using the fractured rock permeability test system. By controlling the axial...
