Abstract: The objective set in the research is the following: to develop the methodology and application tools for assessment of the open-pit excavators engineering level when selecting and designing them for specific mining-geological and technical service conditions. To achieve the objective the methods of statistical data analysis, methods of regression models and of mathematical experimentation building, analysis and synthesis, methods of comprehensive assessment of the engineering level indicators, as well as mathematical modeling and appliance of linear algorithm were used. As a result, the methodology was developed for comprehensive assessment of engineering level and optimization of open-pit shovel excavators parameters, there was also developed a software package, based on the methodology mentioned above, that allowed science-based selection of excavators possessing optimum parameters for the specified conditions.

Key words: open-pit shovel excavator engineering level quality indicators service conditions open-pit mining
