Numerical simulation of dust movement regularities in belt conveyer roadway
Abstract:In order to solve the problem of high dust concentration in belt conveyer roadway,obtain rational parameters for the design of dust removal by ventilation,improve working environment,taking 11/96 belt conveyer inclined shaft of ascension workshop system in Xishimen Iron Ore as the research background,based on the theory of gas-solid two-phase flow,the dust movement was simulated by Fluent software.With the comparison and analysis of field measurement of dust concentration distribution,simulating results were essentially coincident with measured data.The results indicate that wall condition,velocities of belt conveyer and wind are three important factors which impact on dust concentration of belt conveyer roadway.When the velocity of wind in it is the 3 m/s best,dust concentration could keep in 4 mg/m3.Meanwhile,to keep walls moist and decreasing the velocity of belt conveyer could decrease dust concentration too.
