Abstract: Scientific research conducted at the Department of "Mining Machinery and Complexes" has led to the development of recommendations for determining the optimal geometric parameters of the disc tool installed on selective cutting combines. The conducted research included thermal calculations based on the geometry of this tool. The research results allow optimizing the operation of mining combines by identifying the optimal parameters of the disc tool and its geometry. The recommendations are based on the analysis of thermal calculation results and the study of the efficiency of rock mass destruction when using the disc tool. The conducted research contributes to improving the processes of mineral extraction and increasing the efficiency of mining combines. These findings can be applied in the practice of mineral extraction to increase productivity and tool durability, as well as reduce the equipment load. This approach to optimizing the geometric parameters of the disc tool opens up new possibilities for the effective use of combines in complex mining conditions. As a result of the research, it has been established that determining the critical temperature of the disc tool blade is crucial for ensuring the efficient operation of mining combines. Furthermore, the need for forced cooling to optimize the rock fragmentation process has been identified. These findings validate the importance of the correct relationship between the thickness and depth of rock separation when using an asymmetric cutting disk. Therefore, scientific research emphasizes the significance of choosing optimal parameters for the disc tool to ensure efficient operation in mineral extraction conditions. The research is aimed at determining the optimal geometry and operating modes of the disc tool to facilitate effective rock mass fragmentation and enhance the productivity of mining combines.
