Title

Digital Photo-Analysis of Rock Jointing

Abstract

Information can be obtained more quickly, safely and completely from photographs of jointed rock than by climbing over the rock face with a tape and compass. As of 1984, the necessary computer hardware, software and theories of pattern recognition had been developed and used in other disciplines but had yet to be applied to rock. Since that time a research program at the University of Waterloo has made progress towards quantifying parameters such as block sizes, joint spacings and orientations. Work is in progress on measurements of joint roughness and persistence. Envisaged applications include analysis of above- and below-ground excavation stability, of groundwater and contaminant flow, and of blast overbreak and fragmentation.
