Experimental study on influence factors in damage-permeability characteristics of loading and unloading coal

In the process of deep coal seam mining, multiple factors affect the coal body damage-permeability characteristics.In order to reveal the evolution law of coal mining damage-permeability characteristics, the coal damage-permeability experiments under three mechanical paths of fixed confining pressur...
