The report describes a computer program that can model the behavior of assemblages of rock blocks, and visually display this behavior on the screen of a Cathode Ray Tube CRT. There is no restriction on block shapes and no limits to the magnitudes of displacements and rotations that are allowed. The rock geometry is specified by the user, who draws lines on the CRT screen, which is connected to a mini-computer. The program then interprets each closed area between lines as a discrete block, and allows the blocks to move relative to one another, under the action of gravity and forces specified by the user. Joint properties may be specified, and blocks may be excavated, fixed and released, or reinforced.
