摘　　要：煤炭行业的未来发展方向安全、高效、绿色、智能和可持续的发展,提高低质煤的对企业的发展关系重大,本文为了满足低质煤降灰提质的需求,针对低质低质煤的分选并对其实验结果进行了综合分析。通过干法分选低质煤使其在脱粉中回收精煤产品的产率达32.70%。The future development direction of coal industry is safe,efficient,green,intelligent and sustainable development,and improving the low-quality coal is of great importance to the development of enterprises.In order to meet the demand of low-quality coal ash reduction and quality improvement,the separation of low-quality coal and its experimental results are comprehensively analyzed.Through dry separation of low-quality coal,the yield of clean coal recovered in the process of de pulverization reaches 31.80%.
