摘　　要：针对红树梁煤矿选煤厂原生产系统存在的问题,根据选煤厂入选原煤煤质特性,采用新型高效、简化重介分选工艺对该厂进行技术改造,改造后的选煤工艺主要包括原煤智能干选机除杂、超级无压给料双段两产品重介旋流器选煤工艺、煤泥两级回收工艺。生产实践表明,改造后各项技术指标均满足要求,矸石发热量仅为535.04~3218.6 kJ/kg,矸石带煤小于0.15%,改造效果良好,取得了良好的经济社会效益。The Hongshuliang Coal Mine improved the coal preparation process according to the raw coal properties against the existing problems by introducing the high efficiency&streamlined heavy medium separation technology.Updated process includes intelligent dry separator to remove the impurities of raw coal,super gravity-fed 2-stages HMC and 2-stages recovery process of coal slime.New line demonstrates well performance with refuse calorific value 128~770 kcal/kg&coal misplaced content in refuse 0~0.15%and brings exceptional economic social benefits accordingly.
