... contour is numerically simulated during the mechanical integrity test. It is shown that the FTK-simulator can be successfully used to predict the TH2M-couped load-bearing behavior of salt cavern and wellbore throughout its entire life and provides a detailed insight into the development of stress...

... cavern was numerically simulated using COMSOL with the aim to determine the energy losses and the temperature change at the ground surface. The results showed that the energy losses can be reduced considerably by >70% compared to insulated steel tank storages and that the surface temperatures...

ABSTRACT: A mechanised extraction methodology by continuous miner technology is designed for a deep-seated coal seam under massive strata and high in-situ stress conditions by analyzing the stability of rock mass and the rock burst potential through numerical simulation and field investigation...

..., field measurement and numerical simulation. The low strength-stress ratio of the unconsolidated fragment rock mass leads to a very high loose pressure. The measured stresses of the arch have exceeded its strength, which indicates that the arch is less secure. The FEM results show that I18 steel arch...
