Abstract
A cavity monitoring system includes a supporting system adapted to be installed in an access leading to a mined stope, or any other cavity, a mast mounted on the supporting system and adapted to extend into the cavity, and a laser rangefinder mounted at the end of the mast. The laser rangefinder is capable of being rotated around the axis of the mast and directed at the wall of the cavity at angles varying from 0 to 145 degrees from the axis of the mast so as to scan concentric circles on the wall of the cavity permitting a series of distance measurements to be taken to obtain the shape and volume of the cavity.
