Sensory feedback program.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, Contract-C-12458, 1982 Jan; :1-210
This program determined the feasibility of using sensory force feedback on a remote controlled continuous miner to improve operator performance, identified parameters to be sensed and relayed to the operator, and developed a prototype control system for field evaluation. However, due to some unforeseen problems involving machine access by participating mine operators the final phase of the program was changed to one of data gathering and analysis. Sensor equipment was installed on a Joy 12-CM miner located at the Inland Steel Coal Company in Sesser, Illinois. The equipment consisted of two triaxial accelerometer packages, microphone, power and current transducers, signal processor, and power supply. With the full participation of the mine a large volume of data was gathered underground during normal operating shifts, depicting various mining events. Of special interest were cutting sequences which went from the coal to shale interface and those which went from the coal to fire clay interface. Instances of machine stress were also recorded in which the cutter head was caused to stall by forcing it into the coal. Results indicate that some of the parameters indeed exhibit potential to be used for interface and machine stress detection.
