Optimization of the geological resources and mining production models system and its application in Husab uranium mine, Namibia

Based on the existing "2 phases and 3 models" system of Husab uranium mine, this paper proposes and establishes a more systematic and complete "3 phases and 5 models" system, which includes the geological resource model in the geological exploration phase, the medium-term resource model and predictive bench model in the mining design phase and the grade control model and composite model in the mining production stage. This newly established system has substantially improved and optimized the mining production process at the Husab uranium mine, and improved the mine"s production management level and economic benefits.
