Blasthole Grade Control Sytem on Mogolakwena Platinum Mine
Development of a macro menu driven Datamine Studio grade control modelling system for blasthole drilling evaluation by the production geologists on mine. This entailed developing a system that allowed the production geologists to model each blast pattern using the source MS Access database developed by Mr Nick Strydom. A process flow menu was set up to process the data step by step with detailed validations checking the data. The amount of sampled data for the blastholes was monitered and if it was less than 70% of the holes drilled the model was flagged as a preliminary estimate.
3 dimensional models were developed using kriging parameters of the latest resource model for each individual pit. Legends were applied to the models to allow the delineation of grade categories needed for plant feed. The 3d models were converted to 2d and transferred to Autocad (system developed by Peter Nathan) for use by the mine survey department.
A plan was produced for the mine in 2d so the different grade categories could be delineated by tapes for ore loading. This plan was signed off by Geology ,Survey and Mining departments
A software product marketed by GEMCOM and owned by Anglovaal, produced and supported by Marcia van Aswegan. Used by Anglovaal, Anglo American Prospecting Services (AAPS), JCI, Gencor and Goldfields Exploration to log borehole core's geological, sampling and survey data and feed them to spatial modeling packages for mineral evaluation.
3d Grade control modelling for blastholes
Developed a 3d grade control module with Macro's in Datamine Studio 3 for Mogolakwena Platinum mine in Potgietersrust opencasts. For use by the production geologists for grade control and also passed on to the survey deparment for reconcilaition
