Ordinary Kriging was used to evaluate the grade of useful elements of the ore-bodies; the average grade of useful elements and geological reserves were computed statistically. Geological section-drawing was automatically created based on the established geological databases and the 3D models of ore-bodies, faults, stratums and sinking and driving engineering, including manifold graphics element information such as ore-bodies, faults, stratums, laneways, coordinates, scale title bar and so on.
