ASSESSMENT OF ROCK RESISTANCE BASED ON GEOTECHNICAL DRILLING DATA

Abstract

The article discusses the results of assessing the stability of rocks at the Orlovskoye deposit based on geotechnical drilling data. It presents the methods of laboratory testing of rock cores, the characteristics of rock strength and elasticity, and the quality of the rock mass based on the RQD coefficient and the yield of rock cores. Special attention is given to the analysis of the rock's susceptibility to brittle failure based on the UCS/UTS coefficient and the assessment of potential rock bursts. Based on the obtained data, practical recommendations are provided for the design of rock supports in deep and disturbed rock formations. The research results can be used in the modeling, design, and operation of underground mining operations.
