Optimization of Caving Technology in an Extrathick Seam with Longwall Top Coal Caving Mining
The optimization of top coal caving technology is an efficient method to improve the recovery ratio in longwall top coal caving (LTCC). In extrathick coal seams, the conventional single-opening sequential caving technology (SOSCT) shows the following problems: low recovery ratio, high rock mixed rat...
