摘要： A method and apparatus for horizon control in a mining operation is provided. Fresh product 3 is cut from a seam 1. The cutting exposes a fresh cut product face 25. The fresh cut product face 25 is observed at a position immediately adjacent a cutter 11. Any temperature contrast regions from an IR observation between an upper limit of observation and a lower limit of observation are noted. At least one height co-ordinate position of a temperature contrast region 33 is determined and an output signal provided of the determined height co-ordinate position so that the output signal can be used as a horizon datum for horizontal control.
