The dataset is acquried by the in-situ X-ray micro-CT. The acquired radiographic image is composed of 2440 (width) × 2096 (height) pixels in the format of TIFF. The radiographic projection images are reconstructed using NRecon software to obtain the tomographic images.
Abstract null null null null A three-dimensional stress field underground has six independent components. They are among the key factors that affect ground stability. Estimation of the magnitudes and orientations of the 3D in-situ stresses is of practical importance in underground engineering projects. At present the only method that is capable of measuring the complete 3D stresses is the null overcoring null method, which is however expensive and cannot be applied to a deep well in null null pe...
Abstract null null null null In mining operations, blast-induced rock fragmentation affects the productivity and efficiency of null downstream operations null including digging, hauling, crushing, and grinding. Continuous measurement of rock fragmentation is essential for optimizing blast design. Current methods of rock fragmentation analysis rely on either physical screening of blasted rock material or image analysis of the blasted muckpiles; both are time consuming. This study aims to present ...

Abstract null null null The instability caused by the fault slip is one of the main factors that induce the occurrence of coal bursts. To in-depth understand the mechanisms responsible for coal bursts during the underground null coal seam null mining, a mechanical model used to calculate the stress distribution on fault surface and illustrate the fault slip characteristics is proposed by considering the mining-induced stress. In order to verify the validity of this model, a set of comparative an...
Abstract null null null null null Understanding evolution of groundwater hydraulic and chemical conditions is important for safety assessment of null radioactive waste disposal . Perturbations to groundwater can occur due to the construction and operation of the underground facility. The initial perturbations and their recovery after the tunnel closure were observed in the Groundwater REcovery Experiment in Tunnel (GREET) in Mizunami, Japan, at 500-m depth in null null granite . In a 100-m-long ...

Abstract null null null null The grain-scale heterogeneity of rock has been found to greatly affect the null cracking behaviour null null in mechanical tests. However, the heterogeneity has been insufficiently considered in null hydraulic fracturing . To fill the gap, this paper proposes a coupled hydro-grain-based discrete element model and explores the fluid-driven micro-cracking of null null null crystalline rock null null . The micro-heterogeneity of the rock is represented by a grain-based ...
Abstract null null null The coupled Thermo-Hydro-Mechanical (THM) behavior of the Callovo-Oxfordian null claystone null null (COx) is of great importance for the design and safety calculations of the high-level null radioactive waste disposal null project in this potential host rock in France. The heat emitted by the waste causes a null null null pore pressure null null null null null null increase within the surrounding rock essentially due to the differential thermal expansion of the null pore...
