Abstract To explore the strain rate effect of deformation and failure impact prone coal rock, uniaxial compression tests triaxial with different rates were carried out. The mechanical properties tendency impact-prone rock studied, energy evolution law pre-peak self-promotion-inhibition mechanism obtained. results show that increase rate, peak strength under decreases gradually, increases first then decreases, decreases. is mainly divided into four stages: initial damage, hardening, softening...
The failure of rock in cold regions due to repeated freeze–thaw (F-T) cycles and periodic load-induced fatigue damage presents a significant challenge. This study investigates the evolution multi-scale structure fractured granite under combined loading develops constitutive model. results indicate that after F-T cycles, network cracks develop around pre-existing cracks, accompanied by block-like spalling. After applying load, nuclear magnetic resonance (NMR) T2 spectrum shifts right,...
Bedded sandstone is classified as sedimentary rock, which a typical bedded rock with obvious layered structure characteristics. rocks formed different bedding orientations in the long and complicated geological tectonic evolution thus have anisotropic mechanical Therefore, strength anisotropy of depends on dip angles. In this study, fracture characteristics criterion were studied by triaxial compression tests specimens angles under confining pressure. The test results show that failure mode...
Organic-rich lacustrine shales are widely developed in China, and they have long been simply regarded as homogeneous source rocks, which restricts the understanding of intrasource oil accumulation. At present, study LXF (Lower Member Xingouzui Formation) Jianghan Basin an unconventional reservoir is still its infancy, hydrocarbon accumulation mechanism unclear. Geochemical mineralogical studies were carried out on a suite samples from 100-m-thick sequence, i.e., II Oil Bed, by using XRD,...
The Kuqa depression is an important oil and gas production area in western China, there are abundant natural resources the deep ultra‐deep tight reservoirs. In this study, accumulation law of has been systematically discussed based on analysis geochemical parameters, reservoir fluid inclusions recovery burial‐thermal evolution history different structural zones. results show that lacustrine mudstones Triassic Huangshanjie Upper Jurassic Qiakemake formations main oil‐generating source rocks,...
Research on the damage and fracture mechanism of freeze-thaw (F-T) rocks under loading is a key scientific endeavor derived from numerous safety concerns in cold region rock mass engineering. This study analyzed relationship between entire triaxial compression process red sandstone acoustic emission parameters. Based nonlinear growth characteristics cumulative event counts emission, predictive method was proposed for determining crack initiation strength, failure strength F-T sandstone. The...
