Abstract: The purpose of the work is to justify the rational technology of auxiliary mining operations in the opencast coal mines of Kuzbass, to calculate the technological schemes of mining operations in the complex cargo traffic, to study the dynamics of the scheme of stripping. Relevance is caused by that increase of efficiency of results of operations on the basic and auxiliary technological processes is one of the major problems in mining. It is known that auxiliary mining works are carried out by schemes of great variety, At the same time, the development substantiating the rational technology of auxiliary mining operations, until now, is not available. Open pit mining department of Kuzbass State Technical University carried out work on systematization and typification of schemes of auxiliary mining works, based on technological essence of production processes, executed on surface mines, and technological unity of a complex of mining operations in various mining and geological conditions. Rational parameters of technological schemes of auxiliary mining operations are established. Technological schemes of mining of excavator blocks, the dependence of their formation on the order of mining the deposit are determined. Rational technology of auxiliary mining works has been implemented in the production practice of the Chernigovsky surface mine.
