摘　　要：结合目前动力煤市场情况变化和国家环保部门对动力煤洗选要求的提高,探讨了几种可行的脱粉入洗工艺。通过对核心设备的工作原理和结构特点的分析以及各种设备在现场使用效果的调研,初步认为这几种脱粉入洗工艺比目前使用较多的块煤排矸或全入洗工艺更能进一步提高产品质量、减少煤泥量,增加动力煤选煤厂经济效益。According to the change of steam coal market and higher requirements of steam coal preparation by the environmental authority,the paper reviews some cost- effective and workable coal preparation processes after fines-removing. Through the analysis on the principle and structure of core equipment and the investigation of application effect of various equipment,those coal preparation processes after fines- removing are preliminarily regarded as more capable than currently popular techniques,such as gangue removing from lump coals or full coal washing,to enhance product quality,reduce coal slime,and thus to boost the economic benefit to a steam coal preparation plant.
