摘　　要：采用试验测试的方法分析了全尾砂-水泥充填料浆的泌水沉缩特性,结果表明,不同配比及浓度的充填料浆泌水和沉缩量存在较大差异、并遵循着一定的规律,作为指导充填生产核算的重要指标,实践中可结合泌水和沉缩率测试参数计算相关统计量,从而为提高充填效率、降低充填成本、考核充填业绩、制定生产计划提供依据。The bleeding and setting performance of filling slurry were analyzed based on the experiments.The results showed that there were differences in water bleeding volume and setting value among filling slurry with different concentration and cement-tailings ratio,but they followed certain rules.In actual production,the correlation statistics could be accounted according to the tested water bleeding volume and setting value,as the important indexes of filling accounting,so as to provide a basis for increasing the efficiency of filling work,reducing the cost of filling,checking filling work and making production plan.

关 键 词：充填料浆 沉缩率 泌水量 料浆浓度 灰砂比
