The subject of research accomplished at the Institute of Mining, FEB RAS is the Lugiinskoe deposit in Transbaikalia, Russia, intended for mining by opencast method. Regionally, the deposit occurs in the Argun zone of structure formation—Argun terrain—in the Mongol–Okhotsk Fold Belt. The aim of the research was estimation of acoustic wave velocities in oriented core samples from exploratory wells. The data on the acoustic wave velocities allow calculating dynamic Young’s modulus and Poisson’s ratio—the elastic parameters which define the ability of rocks to resist compression and to dilate in axial compression. The resultant estimates of the velocities are presented for different groups of rocks of the Lugiinskoe deposit. The deposit is composed of different types of rocks. Mica present in rocks leads to an increase in their structural looseness and, accordingly, to a decrease in their strength. For different groups of rocks, the depth intervals of the weakest zones are revealed as displacements are possible in these zones in the form of rock falls, caving, landsliding, etc. in the course of mining. The studies on physical and mechanical properties of rocks from their jointing estimates made it possible to develop a geomechanical model of rock mass enclosing the Lugiinskoe deposit, and to detect the most critical sites in terms of stability.
The tests and calculations were performed using equipment of the Scientific Data Processing and Storage Center for Shared Use at the Far Eastern Branch of the Russian Academy of Sciences, supported by the Ministry of Science and Higher Education of the Russian Federation, Project No. 075-15-2021-663.
