全尾砂用于分段空场法嗣后胶结充填的实践

Sublevel Open Stope Method Using of All-tailing Fill with Delayed Cementing

介绍张马屯铁矿采用全尾砂进行分段空场法嗣后胶结充填新工艺的应用情况，总结了取得的经验和不足之处。与原采矿工艺相比，新工艺可大大提高矿石回收率、降低贫化率，而且可充分利用选矿厂的尾矿，不建尾矿库，取得了较大的经济效益和社会、环保效益。

he new technology on a sublevel open stope using all-tailing fill with delayed cementingused in Zhangmatun Iron Mine is presents. As compared with the original mining technology, the newtechnology have many advantages such as raising ore recovery,reducing dilution ratio,fully ultilizing thetailing of concentrating mill and not having to build the tailing pond,and possessing larger economicbenefit, and social and environmental effect.
