Abstract

To achieve the green backfill of an abandoned open pit mine with a large difference chute process system, Fushun West open pit mine is used as the research subject. Based on the theory of gas-solid two-phase flow and the characteristics of large difference chutes, FLUENT numerical simulation software was used to carry out the numerical simulation of the trajectories of dust particles in the chute. The influence factors of the dust movement and the relationship between the factors were explored. The numerical simulation results showed that, the greater the material flow rate, the more serious the resulting dust pollution. The larger the chute angle, the greater the acceleration of the backfill material, and the greater the dust concentration. Therefore, as far as possible, to control the flow rate of the material, a suitable chute angle and U-shaped section of the chute should be selected to control powder or moisture content; these are effective measures by which to reduce dust precipitation.
