... based on the dynamic buckling of rectangular thin plates. When a rock stress wave travels toward a tunnel sidewall, it decomposes into horizontal and vertical components. The horizontal stress propagates to and reflects from the free surface, creating a rectangular thin plate of rock on the surface...

... ABSTRACT In underground mining, stopes are excavated step by step, and each step has a certain length according to the mine planning. Displacements of the free surface of the stope sidewall are contributed by the excavation of stopes. Rockburst is caused by the exaction in underground stopes...

... project is the construction of an underground burial site in Jerusalem. In this project, a layout of large caverns was planned. Along the cavern sidewalls, an array of drilled holes with a 75cm diameter and depth of 230 cm was to be designed. This created a dual-scale problem, which had to be given...
