Abstract
Automation of a mining machine where the operator can be placed in a safe, remote location requires the development of a guidance system. This U.S. Bureau of Mines paper describes a system to determine the position and heading of a mining machine during maneuvers in the face area of an operating mine section. Four linear position transducers mounted on a mining machine with their cables attached to points on a stationary reference were employed, which provided redundancy to increase the reliability of the guidance system. The linear position information obtained from these transducers provides the desired position and heading information, while the algorithm employed utilizes the sensor redundancy to continually test the accuracy of the sensor data. Finally, a preliminary error analysis is performed to identify the major sources of error, which are then evaluated to determine their inaccuracies for use in calculating the overall system accuracy.
