Item type:Item, Analytical Method for Calculating Parameters of Destruction Diagrams of Cylindrical Rock Samples with Their Wedge Form of Destruction(Wroclaw University of Technology, Wroclaw, Poland, 2025) Vasyliev, Leonid; Rizo, Zakhar; Vasyliev, Dmytro; Kress, Denys; Krasovskyi, Ihor; Katan, Volodymyr; Malich, Mykola H.ENG: This study aims to develop an analytical method for calculating the parameters of destruction diagrams of cylindrical rock samples experiencing wedge-shaped fractures, facilitating the effective disintegration of rocks. The method employs analytical modeling to simulate the destruction process of cylindrical rock samples, leveraging experimental values of four key rock properties: shear resistance limit, internal friction coefficient, external friction coefficient, and elastic modulus. The proposed method accurately determines the limit and residual strength of the rock samples using these four indicators, which can be experimentally obtained through straightforward procedures in mining enterprises. This research marks the first instance of analytically modeling the destruction of cylindrical rock samples with wedge-shaped fractures while accounting for both internal and external friction. The practical application of this method allows for the rapid assessment of stress-strain parameters in rock samples, thereby enhancing the efficiency of rock disintegration processes in mining operations.
