Prediction and Assessment of Lateral Displacement of Rock Mass Along the Length of the Horseshoe Cavern – A Numerical Modelling Approach
Abstract: The stability of the underground structures is a key to successful underground mining. Caverns are large underground openings constructed in rock mass for a variety of purposes. The properties of intact rock mass are generally overshadowed by the properties of discontinuities, if the discontinuities are present. Mechanisms of deformation and failure of underground openings in jointed rock mass are determined by the characteristics of the geometrical distribution of discontinuities. This …

Effects of Reinforcing Elements in Soil Reinforcement
Abstract: The inclusion of reinforcing elements in a soil mass improves its geotechnical properties. The principle behind soil reinforcement is that the reinforcing elements absorb the tensile load and shear stress within the reinforced structures and hence prevent the shear failure and settlement. The friction developed between the interface of soil and reinforcing element improves the properties of soil. Different types of natural and synthetic fibers have been used in various …

Some Geomechanical and Petrophysical Linkages Within Paleo-Sedimentary Beds of Ghana
Abstract: Instability issues have been a major challenge in the Sekondian Series of South-Western Ghana. This is particularly affecting civil works and environmental mitigation efforts across the formation as extensive weathered profile impedes structural integrity. Uniaxial Compressive Strength (UCS) of lithological units which is a critical stability measure in most engineering projects requires quality sample of appropriate dimension for its determination. Samples for this important design parameter cannot be easily obtained …
