The present invention discloses an apparatus and method for imaging and clearing an ore pass hang-up. The apparatus includes: a platform that is movable along generally a longitudinal direction of an ore pass; a controllable propulsion unit capable of propelling the platform within the ore pass and to the location of the hang-up; an imaging unit capable of generating an image of the ore pass as the apparatus is moved through the ore pass, wherein the image is transmittable to a remove viewer; extensible, remotely controllable immobilizing units affixed to the platform; and a remotely controllable unit for clearing the ore pass hang-up. Once in place the apparatus is used to break up or clear the hang-up by, for example, directing blows to the hang-up, directing high pressure fluids to the hang-up, and using an explosive charge.
