摘要
尾砂的粒径分布可视为一个灰色系统。在该系统中的一定水灰比条件下，测定不同粒径分布的尾砂胶结充填体各龄期的抗压强度，用灰色系统理论的关联度分析方法定量地表示不同粒径、不同龄期强度贡献的差异，提出了在实际生产中获得最佳尾砂产率的一个指导性原则。
The particle size distribution of tailing can he considered as a gray system. On conditions of certain water-cement ratio in this system,the compressive strength of ce-mented tailing filling body with a different particle seze distribution in individual curingage is determined,the difference in the contribution of varied particle size to strength in in-dividual curing age is expressed quantitatively with correlativity analysis method of thegray system theory,and an instructive principle of optimaI tailing output obtained in thepractical production is provided
