Improving recovery in sublevel top coal caving mining by using partially reverse drawing technique

The sublevel top coal caving (SLTCC) mining technology is extensively employed in steeply inclined thick coal seams. Because of the typical characteristics of the short coal face in this mining method, a significant portion of the top coal is lost at the face end. For reducing the coal loss, the par...
