Raise workings play a key role in the development of ore deposits by ensuring efficient ore transfer, drainage, block preparation, and ventilation. This paper examines the features of driving slot raises for the formation of a slot during drilling and blasting and stoping operations, which are essential for effective ore breakage. At mines in Kazakhstan, raise workings constitute a significant portion of underground excavations; however, traditional methods employing KPV-type raise complexes (Soviet-designed raise excavation systems) and Alimak systems often require substantial time and labor inputs and create increased safety risks for miners. The objective of this study is to assess and substantiate the efficiency of using self-propelled drilling rigs to improve the productivity and safety of drilling and blasting operations in sublevel mining systems. This study presents a comparative techno-economic analysis of the efficiency of using the Sandvik DL210 electro-hydraulic self-propelled drilling rig and the Alimak system for the development of slot raises. The research methodology is based on analytical calculations, mathematical modeling, and comparison of key performance indicators, including drilling rate, equipment setup time, operating costs, number of sublevels, and volumes of mine development workings. The results show that the application of the Sandvik DL210 drilling rig provides a significant increase in drilling rate and a reduction in equipment setup time compared with the Alimak system. It has been established that the efficiency of using the Sandvik DL210 is higher by 27 %, while increasing the sublevel height from 10 m to 20 m allows the volume of mine development workings to be reduced by approximately 50 %. The practical significance of the obtained results lies in their applicability for selecting equipment for raise development at deep horizons of ore deposits, including the Akbakay deposit, with the aim of improving productivity, safety, and economic efficiency of underground mining operations.
