摘　　要：重介质干法选煤技术是目前我国乃至世界缺水干旱地区急需的一种选煤方法,该方法在分选过程中不需用水、分选精度高、投资少、见效快。北京博后公司研发的大型重介质干法选煤系统已在徐矿集团张集煤矿进行工业应用,取得了突破性进展,应用效果良好。The air dense - medium dry coal separation technology is an urgently needed method for sepa- ration of coal in the water - shortage area in China and world. With this method, the separation process no needing of water, has high separation accuracy, less investment and good effect. The large air dense medium dry coal separation system developed by Beijing Bohou Screening Technology Co Ltd has been in- dustrial used in Zhangji coal mine of Xuzhou mining group; It obtained breakthroughs and good applica- tion result.
