ON IMPROVING RECOVERY RATE OF TOP COAL BY SUBLEVEL CAVING MINING IN COMPLEX THICK SEAM
In this paper, the factors of affecting the recovery rate of top coal are analysed and the rational parameters and processes of sublevel caving are discussed. Based on these, effective methods of improving the recovery rate of top coal are presented.
