... on those parameters by using 2D FEM program such as Phase 2 and UDEC. The calculated vertical displacements of cavern roof and wall by FEM analysis were compared with those values monitored during excavation. The calculated axial forces were far below design capacity of rock bolts. The strong rock mass...

... ABSTRACT: This project was supported by Turkish Coal Enterprises and was carried out at the Ilgin-Konya open pit coal mine. Horizontal displacements along boreholes were measured using an inclinometer at 0.5 m intervals. In the same boreholes, vertical displacements were assessed at 3 m...

... where vertical displacements occur due to the deformation (compaction or expansion) of the porous rock formation and its consequent propagation from the subsurface up to the land surface. The aim of this study is to provide a solid probabilistic framework to characterize the geomechanical properties...

... coupled with regional-scale hydro-mechanical simulation models. Simulation results reveal maximum vertical displacements of about 6 mm at the reservoir top and 4 mm at the ground surface. Neither shear nor tensile failure is observed in the hydro-mechanical model at the end of the simulation time...

The maximum vertical and horizontal pressures, calculated using Barton & Grimstad (1993) relations, are 18 MPa and 13 MPa, respectively. Maximum vertical displacement at the Gate chamber roof is 70 cm (Figure...
