  Steepening Pit Walls- Geotechnical and Economic Implications

  By M. Affam, P. Newton

  Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …

  Some Geomechanical and Petrophysical Linkages Within Paleo-Sedimentary Beds of Ghana

  By M. Affam, D. Abdulai, C. Nyarko

  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 …
