Abstract:
The article presents the results of studies to substantiate the optimal parameters of excavator-automobile complexes using mechanical shovels (EAKML) for the conditions of the Kuzbass sections. A number of tasks have been solved in the work: a unified formula has been developed to determine the performance of modern mechanical shovels with a bucket capacity of 6,3 to 55,8 m3 of the weighted average size of blasted rock pieces, the high reliability of which has been confirmed by comparing the calculated values with timing values obtained at the sections as a result of a pilot industrial inspection; an algorithm and methodology for determining the optimal parameters of EAKML was developed; graphical relationships were established between changes in the specific operating costs for the development of one cubic meter of overburden in the conditions of Kuzbass sections and the weighted average size of pieces of blasted rock when using mechlopats with a bucket capacity of 6,3 ÷ 55,8 m3 for rock categories IV and III; an express nomogram method was developed to select the type of excavator or their number in the design or planning of mining operations. The article presents the values of minimum costs and replacement productivity of mechanical shovels in the development of overburden rocks of categories III and IV of EAKML with a bucket capacity of 6,3 ÷ 55,8 m3 for the conditions of the Kuzbass sections corresponding to the optimal working conditions. These recommendations and the methodological approach presented in the work will be useful for both designers and planners of mining enterprises. The use of the results of the work will make it possible to determine the optimal parameters of excavator-automobile complexes using mechanical shovels when re-equipping a quarry to increase the economic efficiency of coal mining.
