It is an important task to generate an efficient operation planning for a modern large scale open-pit mine. Given the depth and the boundary curves of the mine distributions from the boring survey, we introduce a novel method to design the geometry of an open-pit mine. As the first step, the region of interest including the boundary curves of the mine are discretized into 2D voxels. Then, the boundary curves are offset outward using the fast marching method (FMM). The front starts from the voxels that contain boundary curves, and merge each other to form iso-distance contours. For each resulting contour, we elevate the height about 20 m to generate the bench cut with the connecting path having the slope of 10%. We repeat this process until we reach the ground level. Examples show the effectiveness of our method.
