【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 ∑Δpi/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.更多还原
