... of the measured borehole diametrical deformation. One of the key input parameters in this back-analysis method is the borehole convergence. To calculate the convergence, the initially-drilled borehole diameter before deformation is required. The rock mass in the ground is always under stress and a drilled hole...

... ABSTRACT: Surface ground deformations due to mining are dynamic in nature and depend, among others, on the rate of mining. There are many formulations that can calculate and predict ground deformation due to mining. The majority of these models can accurately predict final deformations, i.e...

Advancements in computational power have made it feasible to utilize numerical tools to simulate and analyze complex deformation behavior effectively. Discrete Element Methods (DEM) are more suitable than continuum modeling...

The geomechanical assessment may require the consideration of both reservoir depletion (oil/gas production) and re-pressurization (CO 2 injection) phases, since the reservoir deformation processes during the two phases can be physically linked. In reservoir leakage...
