Ismailova, orcid.org/0000-0003-0273-2304 PECULIARITIES OF DRILLING HARD ROCKS USING HYDRAULIC SHOCK TECHNOLOGY Purpose. To test the theoretical provisions for calculating the geometric and gas-dynamic parameters of a hydropulse apparatus for strikers using core pipes. Methodology. The research methodology is based on the tests carried out. The tests were conducted between January 6, 2021, and April 28, 2021. The type of test is laboratory bench trials. In the course of the study, methods of synthesis and analysis of in- formation were applied. Finding. The basic design parameters of a hydro-pulse generator capable of operating effi ciently with impact machines were obtained during the bench research. The optimal scheme of air fl ow distribution at the exhaust of the hydraulic hammer has been established. The optimal value of the pressure drop in the operating and blocking modes of operation of the generator is deter- mined. In addition, the optimal value of the ejection coeffi cient in these two modes of operation of the generator was determined. Originality. The article investigated the technologies of drilling hard rocks in order to optimise the
