Abstract
Purpose. The primary goal of this study is to analyze current methodologies aimed at significantly improving the efficiency of using drums of mine hoisting machines and reducing the wear of hoisting ropes. The methods is based on the analysis of scientific works by leading experts in the field of mining engineering specializing in the development of mine hoisting machine designs. The literature review includes theoretical and practical aspects of drum design, analysis of different approaches for their rope capacity optimization, and methods to reduce rope wear during operation. Innovative technical solutions proposed in the works of domestic and foreign scientists are studied. Findings. The analysis of scientific works in the field of mine hoisting machines revealed certain shortcomings in approaches to designing and optimizing drum rope capacity. Often, the impact of dynamic loads and material wear during operation, as well as the specifics of drum operation in various mining conditions, is overlooked. This leads to increased risks of breakdowns and reduced safety of hoisting machines. Therefore, there is a need to develop new methodologies that take these aspects into account, ensuring improved quality and reliability of mine hoists. As a result of the study, an innovative drum design with a variable drum diameter was developed, allowing for increased rope capacity and reduced rope wear. The originality. It lies in the formulation of an optimization problem aimed at improving the design parameters of cylindrical drums for mine hoisting machines. This includes the development of innovative algorithms for determining the optimal characteristics of rope capacity, taking into account dynamic and safety factors. Practical implementation. The new drum design developed in the study significantly increases rope capacity, which is a critical aspect for enhancing the efficiency of mine hoisting machines. The optimization of the drum design also contributes to reducing energy consumption during operation, ensuring safer operation of hoisting machines.
