Caving mechanisms of loose top-coal in longwall top-coal caving mining method

International Journal of Rock Mechanics and Mining Sciences, 2014
Abstract The top-coal caving mining method, developed steadily in the past two decades, has become the main method for thick seam coal mining in China. In recent years, the core research areas in the top-coal caving mining are the mechanisms of top-coal caving and the improvement of top-coal recovery ratio.
