After a period of operation imported mining equipment starts failing. As a rule, breakages and critical wear of parts do not involve the entire product, but its individual parts. Despite this, manufacturers of this equipment do not provide repair kits, but offer to change the units and assemblies entirely. As a result, the repair and maintenance of imported equipment imposes significant financial costs. This paper proposes ways to eliminate or reduce the additional costs. The problem solution is based on the determination of the chemical composition and structure of worn out or out-of-order parts, reproduction of their manufacturing technology and production of analogues of these parts in single quantities. The work is performed on the example of high-pressure pump parts and large-sized gears used in mining equipment. For high-pressure pumps, analogues of end sealing gaskets and bearing bushings were made. The obtained experience can be used in the manufacturing and restoration of mining equipment in the Kuzbass enterprises, which allows reducing financial costs and implementing import substitution. The research part of the work was performed in the metallurgical laboratories of KuzSTU, and the reproduction of worn out and out-of-order parts was carried out at enterprises which requested this study.
