This article aims to provide a comprehensive analysis of ways to improve the efficiency of drilling and blasting operations at the Aksu mine, part of the Kvartsit Tauylar deposit in the Akmola region. The objective of the study is to scientifically substantiate effective approaches for optimizing drilling and blasting parameters, taking into account the mine's specific geological and technological conditions. The study comprehensively examines the physical-mechanical properties of the rock mass, the quality of drilling operations, the fragmentation of the blasted rock, and the capabilities of modern digital monitoring systems. Particular emphasis is placed on methods utilizing specific energy consumption during drilling to assess rock drillability. At this stage of the research, the analysis covered geological conditions, drilling quality, drilling and blasting parameters, post-blast fragmentation, and digital monitoring capabilities. In comparison with existing literature, the study highlights the potential of using specific drilling energy consumption as a tool for assessing rock drillability and adapting blasting parameters. The analysis demonstrated the need to adjust drilling pattern parameters, borehole dimensions, and specific explosive consumption based on the properties of the rock mass. As the study is currently in the analytical phase, specific indicators of operational efficiency must be evaluated in the subsequent stage using experimental data. Implementing these approaches in an industrial setting will enable the efficient organization of drilling and blasting operations and the improvement of their technical and economic performance indicators.
