One of the most important factors in the extraction of minerals obtains the maximum benefit. The extraction of minerals is benefit when the more minerals extracted with considering of the technical conditions. In this study, using Flac3D and strain plasticity model, the shape of pillars in Faryab Chromite mine is optimized. In this regard, the pillar of the cylindrical shape was modeled and then the diameter of the cylinder in the middle of the pillar was decreased. The most suitable shape of pillars was obtained with a diameter of the middle 8.6 m and the diameter of the upper and lower 8.8 m.
