%X A three-dimensional nonhydrostatic atmospheric boundary-layer numerical model was used to study the characteristics of flow and turbulence in a small-scale deep open-air mine Considering small scale and complex terrain, in this model we use simple energy closure scheme without hydrostatic approximation A real case of an open-air mine, was simulated Results indicated that the ratio of mine depth to width and the inflow shear obviously affect the flow and turbulence in the pit Some results obtained from this model were in agreement with the wind tunnel experiment under the same conditions
