Abstract

See full text

A method and apparatus for remotely determining the profile of an inaccessible subterranean passage for example in a mine. An instrument pod is moved through the passage in steps. At each step, a rangefinder scans the wall of the passage and provides to a remote monitor, range measurements from which a profile can be determined. The pod also carries clinometers for determining the orientation of the pod during each profile measurement. The pod also carries a television camera and lights so that the wall of the passage can be visually inspected.
