Effect of roof movement on gas flow in an extremely thick coal seam under fully mechanized sublevel caving mining conditions
Abstract The abnormal emission of gas in coals is the main factor that induces serious gas disasters in coal mines. During the coal mining process, roof movement has important effects on the gas emission law and gas flow characteristics. In this study, an extremely thick coal seam under fully mechan...
