Evolution and application of airflow permeability characteristics of gob in roof cutting and pressure releasing mining method

Abstract Cutting roof and release pressure technology has changed the pressure transmission mode of the roof and the caving characteristics of roof rock, which in turn has changed the permeability evolution of the gob. To obtain the permeability characteristics of the gob for the roof cutting and pr...
