Mechanism on particle segregation of rocky cemented fill
摘要
Abstract
A rock particle motion model was established in order to get the stone particles distribution after filling the stope. The model divided particle motion into two stages. The movement of particles in the critical state of the node was identified by mechanical analysis, and analytical expressions forms of particle movement were obtained finally. The relevant factors affecting the segregation were analysed and calculated by this model. The result shows that rock pajlicle segregation can be controlled by adjusting the relevant parameters like the maximum size of rock and chute angle. The result can be applied to mine rocky cemented fill technology.关键词
