Advancement and Development Trend of Filling Technology in Fankou Lead-Zinc Mine

Over the Past 30 years, Fankou Lead-Zinc Mine has made marked achievement in filling technology development. It has ben the leader in China in utilising disposed mill tailings as back fill and has made the traditional hydraulic rockfill technology out Of date. Other advanements include the development of the cement ed rockfill technology and the cemented rod mill sand filling technology . Experiences are also gaind in the mine in research on substitutes for cement. This paper deals with the development and shortcomings of the filling technology in Fankou Mine and discusses its future development trend.
