Author:Van Schoor, MichaelDate:Oct 2021The versatility of ground penetrating radar (GPR) to solving different subsurface detection problems in urban settings is demonstrated. In particular, the advantage of the 3D approach to GPR surveying and how it complements the traditional ...Read more
Author:Van Schoor, Michael; Vogt, DDate:Oct 2013The performance of ground penetrating radar (GPR) under conditions where the ground coupling of the antenna is potentially compromised is investigated. Of particular interest is the effect of increasing the distance between the antennae and ...Read more
Author:Kgarume, Thabang E; Brovko, Fatheela; Van Schoor, MichaelDate:Sep 2015This paper aims to demonstrate, through practical examples and numerical modelling, the trade-off between range and resolution in ground penetrating radar (GPR) prospecting. GPR surveys can easily fail when the target and host rock properties ...Read more
Author:Van Schoor, Michael; Nienaber, WC; Marais-Werner, ADate:Jun 2017A controlled three-dimensional ground penetrating radar monitoring study over simulated clandestine graves was conducted near Pretoria, South Africa, in which the detectability of graves as a function of post-burial interval was assessed, as ...Read more
Author:Grodner, MDate:Sep 2001The depth of mining in the gold mines of the Witwatersrand Basin, South Africa is continuously increasing, with several mines already stopping at depths exceeding 3500m. Due to the high stresses imposed on the rock mass in these deep level ...Read more
Author:Van Schoor, Michael; Fourie, CJSDate:Jul 2008Ground penetrating radar (GPR) and electrical resistance tomography (ERT) surveys were conducted in an urban environment in an attempt to identify the cause of severe structural damage to a historically significant residential property in ...Read more
Author:Vogt, D; Van Schoor, MichaelDate:Oct 2013Ground Penetrating Radar (GPR) is often a good tool for detecting near surface structure, as it is cheap, fast and has high resolution. At lower frequencies, it is an excellent tool for detecting voids such as sinkholes, old excavations or ...Read more
Author:Ogunniyi, Samuel O; Withey, Daniel J; Marais, Stephen T; Crafford, Gerhardus JDate:Jan 2020As mining activities expand into deeper mines in South Africa's geology there are increasing safety concerns for personnel working within these mines. Ground Penetrating Radar can be used to find faults in the rock face; however, current GPR ...Read more
Author:Van Schoor, Michael; Colvin, CDate:Sep 2009In this paper, the application of ground penetrating radar (GPR) for the mapping of near surface tree roots is demonstrated. GPR enables tree roots to be mapped in a non-destructive and cost-effective manner and is therefore a useful prospecting ...Read more
