The paper evaluates the application of integrated scanning technologies for reef identification and mapping in the underground environment. The scanning technologies evaluated includes Light Detection and Ranging (LIDAR), multispectral, ground penetrating radar and thermal scanning technologies to scan a gold reef exposure and platinum reef exposure with the related structural features and geological intrusions. The identification of geological features can facilitate more accurate and detailed mapping of the orebody and provide additional information regarding geological structures and the identification of potential geological hazards. A literature review of current mapping technologies for geology and current scanning technologies including LIDAR, Multispectral and Thermal scanning was conducted. Various scanning technologies were tested on the same baseline and a comparison of efficiency and visibility versus cost and time requirements was made. Studies concluded that geology can be mapped effectively under specific circumstances and can add value in the mapping, inspection and supervision of working underground faces in a narrow tabular mineral deposit.
