Three-Dimensional Modeling of Open-Pit Based on AutoCAD and its Application

Abstract

Three-dimensional geological model of open-pit is an information platform in the construction of digital mine, which plays a significant role in the engineering design and manufacturing management of open-pit. In the AutoCAD platform, take an open-pit for example, it is required to construct a geological database, to construct fault wire-frame model according to the ore body lines, to construct a terrain model according to the present situation map of stope and topographic contour map, to construct coal solid model according to the borehole data and interpolation points, and realize a visible display of a three-dimensional geological model for the open-pit; to construct a block model according to the coal & rock solid model, and add the attribute and assign to it, and then apply it to the calculation of stripping and mining quantities of open-pit. Compared with traditional calculation method, this method is simple in operation, which enhances its calculation speed and precision.
