Add to ORKGAn optical device for following the cut in mining operations is described, and the results of acceptance testing reported. A measuring accuracy of + or - 1/16 inch was demonstrated. Preliminary results on longwall testing with the device mounted on a shearer are presented. Roof profiles measured during tramming and during cutting are presented. Comparison of acoustic measurements with optical measurement of the roof profiles indicates close agreement
