Abstract:

For the low level of mineral resources and reserves dynamic monitoring and mapping in China, a computer-aided mineral resources and reserves dynamic estimation and management model was invented. According to the daily workflow of mine exploration and development, by using point-source database as the basis, mineral resources and reserves integrated and visual dynamic estimating and managing were realized in 2D and 3D space. Problems faced by those complex polymetal mines that mineral resources and reserves dynamic verifying and managing were resolved innovatively by using this model. And it was realized in the traditional method mineral reserves dynamic estimation and management subsystem of digital mine software QuantyMine. Finally, in order to verify this model, using realized subsystem as tool, it was used in some real mines. Took a typical polymetal mine as example, compared dynamic estimation results with mine reserves verification reports, ore weight ranged from -1.78％ to 2.86％, metal weight of Cu ranged from -5.05％ to 4.45％.Those results agreed with the actual reserves of the mine.

Key words: mineral exploration, mineral resource dynamic estimation, digital mine, QuantyMine
