Abstract
The behavior of many types of rock is largely dependent on the fabric of the rock mass. Current methods of manually measuring the discontinuity networks in rock masses are slow, tedious and error prone. The alternative is to make automated measurements of rock jointing parameters on digital images of rock faces in mines, tunnels, and surface excavations.
Photoanalysis techniques are being developed to measure various rock fabric parameters. Techniques presented here include the generation of a joint trace map from a photograph, and the measurement of simple statistics on the joint trace map. Methods are also presented for the determination of block size, both in situ and in muck piles. Finally, a method for measuring the roughness on a joint face using a shadow method is presented.
