The design of a traditional wind curtain dust control device was optimized to overcome its short comings of more equipment, little space, inconvenience in tunnel boring machine's move, etc. In order to ensure the wind curtain dust control device's dust removal effect in practical application, guide the dust control system's design on the spot, and determine the draw-out fan's setting position, a physical and geometrical model was set up according to the roadway head of a Shanxi mine with the proportion of 1:1, and the simulation was conducted by using the computational fluid dynamics (CFD). According to the characteristics of the turbulence model and fluid motion, a Lagrange Discrete Phase Model was selected to simulate and analyze the driving airway dust concentration, and the site practice was conducted. The simulation results showed that the parameters of the physical and geometrical model were selected reasonably, and the fitting precision met the prediction requirement; and the dust concentration decreased obviously after the installation of the new wind curtain dust control device, with the obvious dust-reducing effect if the extraction fans duct was installed at 2.1m from the botton. © 2016, Executive Office of the Journal.
