Evolution of methane permeability and fracture structure of coal: implications for methane extraction in deep coal seams
A traditional view is that gas in the intact coal is easier to be extracted compared with tectonic coal after stress relief. With the increase in buried depth, however, the structure of coal and the permeability evolution law may change. Thus, the variation of permeability characteristics and the ef...
