Application of ∑△pi/di to Optimum Ratio Determination of Effective Silt Particles

    摘要
  • 摘要: 为提高填充料浆质量及指导料浆管输设计,论证了级配特征参数∑△pi/di与极限体积分数Cvm的相关性,得出了粗、细两种充填物料混合后体积分数达到最大值时的级配最佳的结论,并给出了求解极限体积分数的方程组。

     

    Abstract: In order to improve the backfill slurry quality and guide the design of slurry pipeline transportation, the relationship between the size distribution feature parameters ∑△pi/di and the limit solid volume fraction was demonstrated. It is concluded that the size distribution is optimal while the solid volume fraction of the mixed slurry with thick and thin aggregates is maximal. An equation group was proposed to calculate the limit solid volume fraction.
