摘    要：张马屯铁矿位于济南市东郊，地表无处建尾矿库。为了解决这一难题，作者通过一系列试验提出了全尾砂胶结充填方案， 即利用矿山选厂全尾砂作充填骨料， 利用活化搅拌、 泵送和自流输送等工艺， 将高浓度全尾砂胶结充填料浆送入采空区，形成稳定均质结构的充填体。 实践证明， 该方案的实施使矿山实现采矿、 选矿和充填综合平衡闭路循环作业和“无废”生产，成为中国第一座不外排尾矿的矿山。

Abstract: Zhangmatun Iron Mine is situated in the suburbs of Jinan municipality, Shandong. Because of surface environment constraints, no suitable site can be found to build tai lings dams; however the utilization of consolidated tailings backfilling would solve not only the disposal of mineral processing waste, but also the resource of backfilling materials as well as the maximization of ore recovery for the mine. Therefore total tailings backfilling technology, which used blast furnace slag as cement and activating mixing and pump delivery techniques as well, have been developed and reported in the paper. Besides, their application at Zhangmatun Mine was also described.
