Generation And Application Of Fine DEM Of The Open-Pit Mines

The mine digital elevation model( MDEM) is the foundation of spatial information in the digital mine, which provides digital mine plane,three-dimension spatial information. And it provide the powerful support platform for mine layout,the foundation of mine three--dimension model and MGIS. However, at present, people rarely study it. Aiming at the above-mentioned circumstance, this text take example for open-air mine, study the build of fine DEM in the open-air mine, Obtain a series of innovative production: 1 Depending on the topographic map of DWG format, extract a method of establishing elevation data in fine DEM; 2 Adding sidestep attribute to original data, build fine DEM of the open-air mine; 3 Adding restriction condition to built Delaunary triangle net, build fine DEM of the open-air mine; 4 Build grid DEM of the open-air mine; 5 Apply fine DEM of the open-air mine, and the text particularly discusses the arithmetic of diagram layer spliced, and actualize various methods of calculating tonnage of ores and rocks;...
