Systematic principles of surrounding rock control in longwall mining within thick coal seams
Effective surrounding rock control is a prerequisite for realizing safe mining in underground coal mines. In the past three decades, longwall top-coal caving mining (LTCC) and single pass large height longwall mining (SPLL) found expanded usage in extracting thick coal seams in China. The two mining...
