摘要
凡口铅锌矿过去30年在充填工艺技术方面取得显著进步,淘汰了传统的碎石水力充填工艺,在利用造厂废弃尾砂技术方面处于国内领先地位。已取得的进步还有废石胶结充填技术及棒磨砂胶结充填技术,此外,在普通水泥替代物的研究方面也积累了一定经验。本文介绍了该矿充填工艺技术的发展情况,分析了其存在的不足,并就充填工艺发展趋势进行了讨论。
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in China in utilising disposed mill tailings as back fill and has made the traditional hydraulic rockfill technology out Of date.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.
