%X A 3-d non-hydrostatic higher-order turbulence closure numerical model and a random walk method were used to study the characteristics of flow field and pollutant dispersion Meanwhile, the tracer dispersion experiments were conducted in wind tunnel The results of wind tunnel experiments are in good accordance with those of numerical simulations Results show that the pollutant concentration in an open pit is substantially higher than that at the fringe The maximum value is centered upwind the location of the source
