This scientific article focuses on the importance of diamond drilling in the mining industry and its impact on the efficiency of rock breaking processes. The work provides an overview of the classification of rock-breaking tools (RBT) depending on drilling types and rock-breaking principles, offering a wide range of tools for various geological conditions. The main attention is given to diamond crowns and expanders, highlighting their significant role in the well drilling process. The research allows identifying key aspects influencing the efficiency of diamond drilling, such as the optimization of crown designs, real-time slurry size control, and the use of acoustic diagnostics for integral control of the drilling process. In this article, an analysis of changes in the acoustic spectrum during drilling is conducted, revealing diagnostic features of geological strata changes. The formation of slurry particles of a certain size during diamond drilling is noted, emphasizing the need for additional research on the fanulomatric composition of the slurry. The article provides valuable data for improving tool designs and optimizing drilling processes. It is highlighted that additional research in the field of fanulomatric composition of the slurry may lead to a deeper understanding of the impact of rock parameters on slurry particle formation, contributing to the increased efficiency of diamond drilling in various geological conditions.
