Three-Dimensional Model of Cangshang Gold Mine Based on Surpac

The three-dimensional geological model of Cangshang Gold Mine, including the geological database, ore body model and block model, was established by mining software Surpac, which simplified the complicated hand-drawing and reserve calculation. The three-Dimensional development system visualization was also studied on the basis of conducting the vectorization of the whole development system desi...
