The Application And Research Of Surface Mine Simulation Mining Based On VBA With The Secondary Development Of AutoCAD

This article take realizes surface mine three dimensional visible simulation mining as a goal, on the basic of establishment surface mine digitization three dimensional topographical model and coal bed geology model, established of taking the stair as the unit three dimensional lamination type mining model and the mining template, in the AutoCAD platform, developed the strip mine three dimensional visible simulation mining system by VBA, for the surface mine production progress plan establishment, the realization visible design, has provided the effective tool.Through the structure can reflect the mine engineering development condition and the geometry restraint relations mining template, proposed take mining template as the tool level the combination and the localization demonstration simulation method of exploitation; Carries VBA secondary development on AutoCAD for surface mine three dimensional visible geology model system and the surface mine computer-aided design system, fully has used the AutoCAD graphic editor manufacture function, has displayed VBA to the AutoCAD connection support and to the graph analysis computation and graph operation superiority, realizes the digitized surface mine effective technology method.
