摘　　要：黄玉川煤矿选煤厂是神华亿利能源有限责任公司黄玉川煤矿配套新建的一座特大型现代化矿井型选煤厂,目前正处于联合试运转阶段。本文根据黄玉川煤矿选煤厂的实际情况从经济性方面探讨其入选方式。依据原煤年产量及煤种,结合煤矿投产安排,以4号煤单独入选、4号煤和6号煤以不同比例混合入选,以及分级后不同粒级的入选情况拟定出11种方案,经成本计算及各方案的经济概算,确定出入选方式为配煤分级入选(4号煤和6号煤按4∶6混合后的原煤25 mm分级后洗选,其中200～25 mm块煤入选,25～0 mm末煤不洗选,煤泥掺入商品煤中)。Huangyuchuan coal preparation plant, as an appendant project to Huangyuchuan coal mine, is oversize and modern, which is in trial operation phase. To improve its economic benefits, considering the raw coal yield, coal type and normal production time, plan eleven preparation schemes, which are washing No. 4 coal alone, washing the mixture of No. 4 and No. 6 coal. According to the cost calculation, adopt the scheme of preparation of sized blended coal. First blend No. 4 coal and No. 6 coal by the proportion of 4：6 ,then screen the blended raw coal with 25 mm screen, wash the screen overflow （200 mm to 25 ram） rather than the screen underflow （25 mm to 0） , the slime is mixed into commercial coal.
