某铅锌矿使用膏体充填中出现了缓凝现象,添加促凝剂后效果良好。为优化添加促凝剂条件下的膏体物料配比,开展了均匀设计实验。考察了膏体质量分数、砂灰比对泌水率、流动度、充填倍线、膏体强度的影响。实验结果表明,膏体的泌水率、流动度和充填倍线主要受质量分数影响,且均与浓度成负相关。砂灰比对流动度的影响很小,但其是膏体强度的主要影响因素,砂灰比越小,膏体的强度越大。综合考察泌水率、流动度、充填倍线、膏体强度4 种指标对应的配比范围,得出推荐配比为质量分数75%~76%、砂灰比7:1~8:1。
The retarding phenomenon appeared in the paste filling of a lead-zinc mine and it was ameliorated after adding coagulants. To optimize the paste material ratio under addition of coagulants, we carried out a uniform design experiment. The effects of paste concentration and sand-cement ratio on bleeding rate, fluidity, backfill gradient and paste strength were investigated. The results show that the paste bleeding rate, fluidity and backfill gradient were mainly influenced by concentration, and they were negatively correlated with the concentration. The sand-cement radio had a small impact on fluidity but a major impact on paste concentration. The smaller the sandcement ratio was, the larger the intensity of paste was. Based on the ratio ranges corresponding to the four indices of bleeding rate, fluidity, backfill gradient, and paste strength, the recommended ratio is 75% to 76% and the sand-cement ratio is 7:1 to 8:1.
