Abstract The collection of reliable information for improving the design of underground excavations is a major problem in underground mines where boulders that detach from the rock mass can cause serious injuries. This report describes an image analysis system adapted to the conditions in underground mines. Compared to the traditional method of discontinuity surveys, this technique offers many advantages: the time necessary for data acquisition is greatly reduced; the large amount of data collected increases the quality of the information available for characterizing the rock mass; it allows the creation of a permanent database; it is simple to implement; and mainly, it avoids the operator's direct exposure to falling boulders.
