摘 要: 張馬屯鐵礦位于濟(jì)南市東郊，地表無處建尾礦庫。為了解決這一難題，作者通過一系列試驗(yàn)提出了全尾砂膠結(jié)充填方案， 即利用礦山選廠全尾砂作充填骨料， 利用活化攪拌、 泵送和自流輸送等工藝， 將高濃度全尾砂膠結(jié)充填料漿送入采空區(qū)，形成穩(wěn)定均質(zhì)結(jié)構(gòu)的充填體。 實(shí)踐證明， 該方案的實(shí)施使礦山實(shí)現(xiàn)采礦、 選礦和充填綜合平衡閉路循環(huán)作業(yè)和“無廢”生產(chǎn)，成為中國第一座不外排尾礦的礦山。

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.
Key words: tailings dam total tailings consolidated backfill activating mixing slag
