摘要
针对保德煤矿采煤方法由连采、综采调整为综采放顶煤开采工艺导致的原煤煤质急剧变差,给保德选煤厂原有工艺系统造成诸多不利影响的状况,结合该厂生产实际,对原煤系统、分选系统、煤泥水系统等相关工艺环节进行了技术改造,取得了良好的生产效果。
Due to mining process in Baode coal mine was changed from continuous fully mechanized min- ing to caving mining, which caused deterioration of raw coal quality, brought the adverse effect to the ex-isting coal preparation system. Based on production practice, by conduct the technical innovation on raw coal system, separation system and the coal slurry system, the coal preparation plant obtained good pro-duction effects.
