In the context of advancements in deep resource development and underground space utilisation, engineering faces challenge investigating mechanical behaviour rocks under high-stress conditions. The present study is based on a gold mine, bulk ore taken from mine perimeter rock was processed into two sets specimens containing semicircular arched roadways with half full penetrations. tests were carried out using true triaxial test system. results indicate that stress–strain curve included...
In this paper, the shear modulus and damping ratio of silica rock under cyclic loading were experimentally analyzed using two modes, constant amplitude increasing amplitude, combined with three rates. Observations have indicated a decrease in specimens as number cycles increased during unloading phases an overall increase larger intervals. The change rate significantly affects specimens, leading to stepwise within same group, while single specimen exhibits ‘concave’ distribution throughout...
To quantitatively study the failure evolution characteristics of raw coal and briquette under triaxial compression, an acoustic emission (AE) experiment was conducted on both materials. The characterized based AE energy. A constitutive model accurately describing process constructed. Using Logistic function, a compression constructed by combining mechanics theory with effective medium theory. effects parameters r relationship were further analyzed. results show that compaction stage is more...
ABSTRACT The aim of this work is to investigate the deformation and energy characteristics skarn with different interlayer inclination angles under cyclic loading. samples marble bands various orientations (i.e., 30°, 45°, 60°, 75°) were chosen as test material. It revealed from testing results that presence interlayers changes geomechanical properties rock, rock peak strength, elastic modulus increases increasing angle. Additionally, growth rate input exhibits an inverted “V” pattern...
The reasonable determination of the coal rock stress threshold holds significant importance for objective description deformation stages and fine-scale crack evolution during failure. This study aims to accurately identify raw briquette propagation under triaxial compression determine suitable identification methods. thresholds were determined via experiments, coupled with monitoring stress, strain, acoustic emission (AE) signals. was achieved by employing axial strain method, moving point...
