Enhancement of open-pit mining efficiency by means of quality improvement of open-pit excavators design and operating in specified conditions

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, there was developed the methodology of comprehensive assessment of engineering level and parameters optimization of open-pit shovel excavators, there was also developed a software package, based on the methodology mentioned above, that allows science-based selection of excavators that possess optimum parameters for the specified conditions.
