Laser Alinement Sensor for Continuous-Mining Machines.

Abstract	Presently used techniques for guiding a continuous mining machine while advancing an entry are not totally satisfactory. The machine operator guides the mining machine by observing a line painted or chalked on the mine roof. Errors in entry bearing and alignment result from this method. Thus an improved system for guiding a continuous mining machine under manual control is desired and becomes a necessity when remote or automatic controls are being used. The control of continuous mining machines from a remote location provides safety and production benefits but presents additional guidance problems. Visibility of the machine by the operator is impaired by distance and other environmental conditions. Therefore it is necessary to provide a remote operator a readout at his position to show the exact location and attitude of the machine. Automatic control of mining machines make additional demands on an alignment system; the alignment sensors must be included as part of the feedback loop in the automatic steering system. This report describes an alignment sensor system for use on continuous mining machines.
