..., and the compatibility between support elements. Rock support elements are loaded dynamically owing to the energy release during rock excavation and statically by the deadweight of potentially falling blocks afterward. In highly stressed rock masses, the dynamic load on the support elements is not a constant...

... process involves additional investigations during construction for hot spots, 3D geometrical analysis, geotechnical assessment of the cavern and verification of rock supports by detailed geotechnical back analysis using actual excavated data from water curtain and cavern heading. The geological model...

..., Chennai-2, E-mail: [email protected] ABSTRACT : Design and construction of under ground cavern involves fixing the size, layout and orientation of cavern, design of rock support, blasting pattern, excavation sequence, rock support, instrumentation etc. This is a case study paper on planning, design...
