To address the problems of weak research on solidification and slurry properties of classified overflow fine tailings and slow progress in underground backfill treatment of fine tailings, a small spread cylinder was used to measure the spread value to determine the paste backfill concentration. Using slag-based cementitious materials, solidification tests and slurry property studies were carried out on ultrafine tailings from middling overflow of an iron mine, classified overflow fine tailings from some gold mines, and unclassified tailings from several iron mines. The results show that the use of slag-based cementitious powder can effectively solve the problems related to the solidification and strength requirements of classified overflow ultrafine tailings. Ultrafine tailings have high porosity and low bulk density, and the slurry mass concentration can be as low as below 50%. Under the same binder dosage, the cement-tailing ratio of ultrafine tailings is relatively high, but the 28-day strength loss of the backfill is limited, and the increase in backfill cost is not significant. The slurry mass concentration has a significant effect on solidification strength. Under a filling line of 3.5 to 4.0, the ultrafine tailings backfill slurry can achieve gravity flow transportation without pumping.

针对分级溢流细尾砂固化与料浆特性研究薄弱、井下充填处理细尾砂推进缓慢的问题，采用小扩散桶测定扩散度以确定膏体充填浓度，应用矿渣基胶凝材料，开展了某铁矿中矿溢流超细尾砂、部分黄金矿山分级溢流细尾砂及多座铁矿全尾砂的固化试验与料浆特性研究。结果表明：使用矿渣基胶固粉可有效解决分级溢流超细尾砂固化与强度需求方面的问题；超细尾砂孔隙率高、堆积密度小，料浆质量浓度可低至50%以下；相同胶固粉用量下，超细尾砂灰砂比较高，但充填体28 d强度损失有限，充填成本增幅不大；料浆质量浓度对固化强度影响显著。在3.5~4.0充填倍线下，超细尾砂充填料浆可实现自流输送，无需泵送。
