Abstract
The text substantiates the dependence of the complex dimen-sions of and transportation equipment (excavator - dump truck links) on the parameters of the mining method, which ensures an increase in the effi-ciency of open-pit mining of mineral deposits, is justified in the text. In-creasing the efficiency of open-pit mining method using a complex of ex-traction and loading and transportation equipment is achieved by increasing the range of permissible parameters of the mining method. The study allowed to identify the dimensions of the extraction and loading and transportation equipment complex (excavator - dump truck links) affect the height of the bench and the width of the working platform the dimensions of the mining and loading equipment (excavator - dump truck links) are the main indicators that affect the parameters of the mining method at the complex of mining and loading and transportation equipment.
Highlights
Opencast mining is developing in the direction connected with using more advanced equipment which significantly bigger linear dimensions
The most popular extraction and loading equipment used in open pits is a mechanical shovel of excavator type
Opencast mining is developing in the direction thatis associated with the use of a more advanced equipment that has significantly bigger dimensions, which leads to an increase in the parameters of the mining method
Summary
Opencast mining is developing in the direction connected with using more advanced equipment which significantly bigger linear dimensions. This leads to an increase in the parameters of the mining method. Of the main technological processes in the development of mineral deposits of the open type, we can distinguish two processes that have a greater influence on the mining method parameters: extraction and loading and transportation of rock mass [1,2,3]. Analysis of the trend of using excavators in the development of opencast mineral deposits has shown an increase in the number of powerful quarry excavators with working equipment backhoe hydraulic excavators and rope excavator with a front shovel [4,5].
