A CASE FOR TERRESTRIAL PHOTOGRAMMETRY IN DEEP-MINE ROCK STRUCTURE STUDIES

A method of rock fracture orientation mapping by photogrammetric means is detailed. The technique is particularly useful for statistical studies of fracture patterns in the often confined and uncomfortable underground environment. The advantages of convenience, efficiency and high accuracy of dip and dip direction measurements are stressed. Sections are devoted to the background theory of terrestrial photogrammetry, a description of the unsophisticated photographic equipment used and the actual procedure, which involves certain external control measures. Photo-interpretion, data entry and processing, with the aid of a stereoscope, digitizer and mini-computer, are outlined. Two sources of error are analysed. A section on results outlines laboratory and field tests which show negligible errors in fracture dip and orientation angle determinations. (Author/TRRL)
