文章亮点

(1) SNF的存在增加了RCPB浆料的屈服应力。

(2) 新鲜RCPB的泌水率随着SNF用量的增加先下降后上升。

(3) SNF显著改善了RCPB固化7天和14天的早期UCS，但阻碍了固化28天样品的UCS发展。

(4) SNF加速了RCPB的水化反应，增加了水化产物的数量，缩小了孔径，压实了样品的微观结构。

中文摘要

棒磨砂（RMS）是一种可以制备棒磨砂基胶结膏充填材料（RCPB）的粗砂骨料，主要用于金川镍矿地下矿区的胶结膏体充填（CPB）。众所周知，粗颗粒通过管道输送到地下采场会导致回填系统稳定性减弱。因此，磺化萘甲醛（SNF）缩合物常被用于RCPB性能的改善。本文研究了固含量（SC）、灰砂比和 SNF 用量对流变和物理力学性能的协同影响，包括坍落度、屈服应力、泌水率、单轴抗压强度（UCS），以及 RCPB 的机理分析。结果表明，SNF 对 RCPB 性能的影响与 SNF 用量、石灰砂比和 SC 有关。含有 0.1wt%–0.5wt% SNF 的新鲜 RCPB 的坍落度增加了 2.6%–26.2%，而屈服应力降低了 4.1%–50.3%，表明混合料的可加工性和粘结性更好。新鲜RCPB的泌水率随着SNF用量的增加先下降后上升，下降峰值为67.67%。此外，RCPB的UCS会随SNF用量的增加先升高后降低。在0.3wt%的最佳SNF添加比例下，RCPB养护7、14和28 d的UCS分别提高了31.5%、28.4%和29.5%。结果表明SNF 有利于增强 RCPB 早期的UCS 。但是，后期的UCS以较慢的速度增加。研究结果可以指导具有实际应用性能的 RCPB 的设计和制备。

Abstract

Abstract

Rod milling sand (RMS)—a coarse sand aggregate—was recycled for cemented paste backfill (CPB) for the underground mined area at the Jinchuan nickel deposit, named rod milling sand-based cemented paste backfill (RCPB). The adverse effects of coarse particles on the transportation of CPB slurry through pipelines to underground stopes resulting in weakening of the stability of the backfill system are well known. Therefore, sulfonated naphthalene formaldehyde (SNF) condensate was used for the performance improvement of RCPB. The synergistic effect of solid content (SC), lime-to-sand ratio, and SNF dosage on the rheological and physicomechanical properties, including slump, yield stress, bleeding rate, uniaxial compressive strength (UCS), as well as mechanism analysis of RCPB, have been explored. The results indicate that the effect of SNF on RCPB performance is related to the SNF dosage, lime-to-sand ratio, and SC. The slump of fresh RCPB with 0.1wt%–0.5wt% SNF increased by 2.6%–26.2%, whereas the yield stress reduced by 4.1%–50.3%, indicating better workability and improved cohesiveness of the mix. The bleeding rate of fresh RCPB decreased first and then rose with the increase of SNF dosage, and the peak decrease was 67.67%. UCS of RCPB first increased and then decreased with the increase of SNF dosage. At the optimal SNF addition ratio of 0.3wt%, the UCS of RCPB curing for 7, 14 and, 28 d ages increased by 31.5%, 28.4%, and 29.5%, respectively. The beneficial effects of SNF in enhancing the early UCS of RCPB have been corroborated. However, the later UCS increases at a slower rate. The research findings may guide the design and preparation of RCPB with adequate performance for practical applications.
