The relevance of this study stems from the critical role that groundwater plays in providing the population with high-quality drinking water. Groundwater is extensively utilized for industrial purposes, housing and communal services, irrigation of pastures, and other needs. The study aims to explore the specifics of drilling hard rocks using hydraulic impact technology. The research methodology is based on laboratory bench tests conducted from January 6, 2021, to April 28, 2021, at the educational and production workshops of the Department of «Technological Machines and Equipment» at the Mining and Metallurgical Institute of the National Academy of Sciences «KazNITU named after K.I. Satpayev». The research also incorporated methods of synthesis and information analysis, and at the final stage, an analysis of scientific literature on the subject was conducted. The bench tests yielded the main design parameters of a hydraulic pulse generator effective for use with impact machines, including the main geometric parameter Fd/FK (3.78), ld - 70-100 mm, 1h=35 mm, 1c=24-30 mm, FKp=254.34 mm², Rd=981.25 mm², and F=304.72 mm². The tests aimed to optimize the primary geometric parameters of the hydraulic pulse generator, analyze the distribution of the working flow in front of the jet apparatus, and measure the ejection coefficient and pressure drop to refine the experimental setup for downhole conditions. The practical significance of this research is that it serves as a foundational study for further exploration of hard rock drilling using hydraulic impact technology, benefiting both practitioners and theorists in the field.
