改进放煤工艺提高煤质和回收率

Raising Coal Quality and Recovery Ratio with Improving Caving Coal Craft

分析了煤炭回收率和煤质之间的关系,针对米村矿28041采煤工作面的煤层情况,通过实验、分析,在不降低回收率的同时改进放煤工艺,从而提高煤质,提高煤炭吨值,具有一定的借鉴价值。

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.
