IMPROVING THE QUALITY OF ORE CRUSHING DURING DOWNHOLE EXTRACTION USING THE MICROMINE PROGRAM OF THE ZHOLYMBET DEPOSIT

This study aimed to enhance ore fragmentation quality during blast hole drilling using the Micromine software. During the implementation of this goal, several challenges arose that were beyond the control of the drilling and blasting engineer. Specifically, the absence of a lithological block model from the geological department was a significant obstacle. Furthermore, the geomechanical department reported that creating a block model was not feasible, and the ShotPlus software did not support the format initially intended by the geomechanical team. ShotPlus representatives also confirmed that their software was not designed for geomechanical block modeling. Given this situation, it was decided to provide the geomechanical information in written and graphical forms after mapping. Despite these limitations, the use of Micromine software allowed for improvements in ore fragmentation parameters, confirming the effectiveness of this technology.
