It is considered that land deformation caused by open-cut mining influences on wind system around the quarry. Two case studies were conducted to investigate the change of wind system around the quarry.The results are summarized as follows:(1) Land deformations caused by open-cut mining were simulated with three dimensional computer graphics, and it became possible to forecast the changes of wind direction visually.(2) By use of quantitative formula that showed the relationship between lay of land and wind direction frequency, it became possible to forecast the changes of prevailing wind direction and wind direction frequency quantitatively.(3) It became clear that deforestation according to open-cut mining influenced on increase of wind speed around the quarry.(4) In case A, the ridge of the quarry will be mined, it was forecasted that change of wind system affected on living environment a little.(5) In case B, all over the mountain will be mined-out, it was forecasted that wind system around the quarry was changed widely.
