Assessment and prospects for improving the technical level of surface mining machines

Assessment of the technical level of surface mining machines is carried out according to a special method of expert-free assessment of min- ing machine quality, known as the G.I. Solod’s technique. The technique is based on the basic principles of qualimetry and allows to assess functional- ly homogeneous machines of different sizes, types and designs based on the functional criterion of the machine that determines its main purpose. Assessment of the technical level of mining machines creates the basis for choosing priority areas for its improvement and development of scientifi- cally-based methods for the optimal design of machines. In this regard, the aim of the work is a comprehensive assessment of the technical level of surface mining machines to increase it and optimize their parameters. For this, methods of mathematical modeling, statistics, data collection and pro- cessing, analysis and synthesis were used. The developed methodology for integrated assessment provides the ability to control the quality of a surface mining machine at all stages of its life cycle: design, manufacture, opera- tion
