The article presents the main advantages of electric hydraulic drilling method. During the drilling, the wear of the metal parts of the drill electrodes takes place. In the course of the investigation, the authors determined the dependences of the electrode wear rate on both the energy parameters and the number of electro-hydraulic pulses. Using the analysis of the experimental data, the optimal values of electrophysical parameters provided by the metal electrode system, for which an intensive destruction of solid rock takes place, are determined. Based on microscopic images, the areas of the electrode surface melted under the underwater spark discharge are investigated. The proposed electric hydraulic drill makes it possible to destroy and crush hard stones more efficiently by means of the electro-hydraulic discharge during well drilling.

Key words: wear of electrodes' metal, electric discharge, metal electrode system, electric hydraulic drill.
