Study on Roof-Coal Caving Characteristics with Complicated Structure by Fully Mechanized Caving Mining
With mining technology and mechanization degree being improving, fully mechanized caving mining technology (FCM) has become a main method for thick coal seam extraction in China. However, roof-coal caving characteristics in turn restrict its recovery efficiency, especially for the coal seam with com...
