关键词:Blasting effects of crossfault deepburied excavation on adjacent existing tunnel stability
摘要:AbstractThe vibration caused by blasting excavation of rock mass frequently poses a threat to the stability of adjacent tunnels. Previous research is limited by the simplification of a rock mass as a homogeneous elastic medium, without considering the wave attenuation caused by viscoelasticity and wave separation induced by rock discontinuities, as well as plane waves while neglecting geometric...

关键词:Investigation of the failure characteristics fissure tunnels under dynamic and static combinations
摘要:AbstractConsidering the expansion of mining operations into increasingly deeper areas, it is imperative to assess the influence of dynamic disturbance loads on the security of deep tunnels. Here, via AUTODYN finite difference software, a numerical analysis of the fracture characteristics of a fractured tunnel was employed under the coupled action of in-situ stress and dynamic disturbance loads....

关键词:Strainbased modeling and analysis for rock blasting geomechanics applications
摘要:AbstractPredicting rock blasting outcomes in mining has been crucial since its inception. Blasting remains the most energy- and cost-efficient method for rock breaking and is often the only practical option. However, the mechanism is complex, influenced by various rock properties, explosives, and blast design parameters, making their effects difficult to quantify. Traditional stress-based model...

摘要:AbstractIn hospitals, a medical computed tomography (CT) scan is used to detect damage to infected areas of the human body. Using this technology, scientists and engineers have found a way to detect the internal pore connections and characterize rock samples of oil and gas reservoirs in the petroleum industry. Nowadays, the micro-CT scan technique is gaining considerable interest in reservoir r...
