Alkali residue, a solid waste with potential cementitious properties, poses severe environmental risks when piled in a large amount. To enable large-scale utilization of alkali residue, this study partially replaced cement with alkali residue to prepare alkali residue modified cemented backfill. Dynamic impact tests were conducted to investigate mechanical behavior and energy evolution characteristics of alkali residue modified cemented backfill. Results indicated that incorporation of alkali residue altered the mechanical performance and enhanced compressive strength of the backfill. With increasing alkali residue replacement proportion, compressive strength first increased and then decreased, peaking at an alkali residue replacement proportion of 5%. Energy evolution of alkali residue modified backfill can be categorized into three stages: linear elastic stage, plastic yield stage, and instable failure propagation stage. Addition of alkali residue brought elastic strain energy closer to total input energy during the first stage, reduced instances of negative dissipated energy, and rendered the energy curves more physically realistic. As alkali residue content increased, the maximum elastic strain energy initially rose and then declined, reaching its peak at an alkali residue replacement proportion of 5%. These findings demonstrated that alkali residue improved mechanical performance of cemented backfill, thereby providing a theoretical basis for the application of alkali residue in mine backfilling operations.

碱渣作为具有潜在胶凝特性的固体废弃物，大量堆积会严重污染环境。为大规模利用碱渣，本研究采用碱渣取代部分水泥制备碱渣改性尾砂胶结充填体，对碱渣-水泥基尾砂胶结充填体进行冲击试验，探究碱渣改性尾砂胶结充填体的力学性能和能量特征。结果表明：碱渣改变了充填体的力学性能，提高了充填体的抗压强度。随着碱渣取代率的增加，碱渣改性尾砂胶结充填体的抗压强度先增加后减小，在碱渣取代率为5%时最高。碱渣改性尾砂胶结充填体的能量特征主要分为线弹性阶段、塑性屈服阶段和失稳破坏增长阶段3个阶段。碱渣使得第一阶段的弹性应变能更加趋近于总能量，耗散能为负的现象减少，能量曲线更趋近于真实状态。随着碱渣的加入，充填体的弹性应变能最大值先增加后减小，在碱渣取代率为5%时达到最大，这表明碱渣改善了充填体的力学性能，为碱渣在矿山上的应用奠定了理论基础。
