| Abstract: | The relation between the coal recovery rate and the coal quality is analyzed. Aimed at the coal seam circumstance in 28041 working face of micun coal, through experiment and analysis, at the time of not lowering the recovery rate, improving caving coal craft, the coal quality and tonnage raise. It has certainly reference Valum. |
