| Popis: | Due to the inherent hazardous characteristics associated with dolomite and development on dolomite, quantification of the stability attributes related to dolomite is essential. In large parts of South Africa, development on dolomite is inevitable due to the location thereof. The purpose of this study is to define an implementation framework for decision-making with regards to development on dolomite. The decision-making process is based on a dolomite stability investigation conducted by AGES North West (AGES, 2012) within Sarafina, Ikageng. The results from this study are interpreted by means of a decision support system that is based on the geo-environmental setting of the study area and the geotechnical properties related to the subsurface profile. This includes but is not limited to: Geo-environmental site conditions: • Drainage • Topography • Geophysical conditions • Regional geological conditions • Local geological conditions • Regional groundwater conditions • Local groundwater conditions Geotechnical stability of the dolomite based on the hazard characterisation and evaluation procedures: • Percussion drilling data • Receptacle development • Mobilisation agencies • Potential surface manifestation development space • Nature and mobilisation potential of the blanketing layer • The bedrock morphology These parameters are all inter-related and affect each other in various ways. During the study the importance of site specific observations and interpretations are emphasized. Thesis (MSc (Environmental Sciences))--North-West University, Potchefstroom Campus, 2013 |
