Abstract. The article presents a 3D model of the staged contours of round and oval quarries with certain slopes of their sides formed during development of the steep deposits. In each horizon, a contour stage presents a close line. After analyzing the field digital model, a zero horizon contour is determined for future mining operations. Further, a polar point of the zero horizon and polar axis are assigned. Then, each time, a polar angle is counted counter-clockwise from the polar axis. Fur-ther, each arc and contour surface are replaced by a spline. Thus, the mathematical model takes into account alignment of the ore body with the pit staged contour. The 3D model of the staged quarry contour takes into account configuration of the ore body and slope of the pit walls by applying one-dimensional spline of the second order for the horizontal sections and two-dimensional spline for describing side surfaces of the ore body.

Keywords: quarry staged contours, steep deposits, 3D modeling, mining operation mode, stripping ratio, one-dimensional and two-dimensional spline.
