This paper analyzes ore delivery methods suitable for the deep-level mining environments of the Kryvbas region. The study focuses on the feasibility and economic advantages of utilizing a combined scraper-self-propelled ore delivery system within sublevel caving operations. Through comprehensive analysis, it is found that the integration of self-propelled equipment significantly enhances the efficiency and cost-effectiveness of ore transport. The proposed delivery method involves using multi-bucket scraper winches for primary ore movement and deploying a self-propelled load-haul-dump (LHD) machine for secondary transport. Economic and mathematical modeling results demonstrate that this combined approach enables optimization of operational parameters, identifying the most effective application ranges for different types of self-propelled LHDs in secondary ore transport. Specifically, the study highlights that the ST7 model of self-propelled LHD is the most cost-effective solution for secondary transport, minimizing specific delivery costs while maintaining productivity. Additionally, the findings provide practical guidance on the optimal usage limits for various self-propelled LHD types, helping to inform equipment selection for enhanced operational efficiency in caving systems. These insights contribute to improved decision-making in mining operations, promoting both economic and technical benefits in high-depth mining scenarios.
