Study on the Failure Characteristics of Coal Wall Spalling in Thick Coal Seam with Gangue
Coal wall spalling is one of the main factors restricting the safe and efficient mining of thick coal seam, and the gangue has an important impact on the coal wall spalling. To obtain the failure characteristics of coal wall spalling in thick coal seam containing gangue, numerical calculation and th...
