尾砂膏体饱和率与泌水率的计算方法

摘要

借助三相比率指标模型,定量推导出集料饱和率和泌水率的理论计算公式.通过理论分析计算得出,当料浆饱和率为101％～ 108％,泌水率为1％～7％,即构成合格的膏体,从而为膏体的判别提供理论依据.以某铜矿膏体充填为背景,通过试验验证了该公式具有较高的可靠性.%In this paper,the theoretical calculation formula of aggregate saturation rate and bleeding rate is deduced quantitatively by using the three-phase ratio index model of aggregate.According to the theoretical analysis and calculation,a qualified paste would form when the slurry saturation range is 101％ ～108％,and the bleeding rate is in the range of 1％ ～ 7％,which provides a theoretical basis for the paste determination.The gap between theoretically calculated and measured values is analyzed by experiment,and it is confirmed that the formula has high reliability.
