This research project attempts to identify, by means of a literature survey, different exploration and geophysical methods that could be used to detect dykes ahead of underground coal mine workings. In this study a range of geophysical and exploration methods have been identified which are generally used in the mining industry. As a result at the present most South African coal operations use a combination of vertical drilling, aeromagnetic surveying and in-seam drilling techniques to detect and identify the presence of dykes ahead of the mining face with a relative high degree of accuracy.
