The conditions of operation of the parts and components of mining equipment, which are made mostly from 110G13L steel, are considered. Limited possibilities for application of this steel to improve the equipment service life are noted. The possibility of application of electroslag surfacing in a current-conducting mould by different high-carbon materials is shown as an alternative. High-chromium cast irons should be considered the most promising surfacing material. They have a good combination of higher mechanical properties and resistance to abrasive and shock-abrasive wear. 24 Ref., 2 Tabl., 1 Fig.
Keywords: parts of mining equipment, wear, electroslag surfacing, current-conducting mould, 110G13L steel, high-chromium cast iron, high-speed steel
