摘要
本文从我国高硫难选煤多的煤质特点、合理利用煤炭资源、保护环境、煤炭深加工的必要基础、节能、节运及提高经济和社会效益等方面，分析论述了选煤在洁净煤技术中的重要地位和作用；介绍了国外洁净煤技术的研究现状，指出了目前对极细粒级煤分选有工业实用价值的选煤方法；综合分析了我国目前洁净选煤技术的研究情况及与国际水平和生产建设要求的差距，提出了我国今后的研究重点。
The majority of the run-of mine coal produced in China is hard-to-wash ,high-sulphur coals , and coal preparation constitutes in this case a key link in striving for rational utilization of coal ,environmental protection and in-depth coal processing operation. Following a general analysis of the position and role of coal preparation in clean coal technology on the basis of energy conservation, reduced load on transportation , and improved economic and social benefits,the paper pre-sents an overview of the present status of research activities on clean coal technolo-gy in overseas countries ,commercially attractive washing methods in current use for effectively treating the ultra-fine coal. An analysis is also made of the CCT research efforts so far made in China ,and the gap in comparision with international level and production requirement. Finally the authors point out the key research programs to be pursued in China in the future.
