Improved Dragline Utilization
MetadataShow full item record
The cause of energy conservation can be served by increasing the efficiency of large draglines used in surface coal mining. The topic is the application of a training simulator, computer instrumentation and computer simulation to improve dragline operator skill, decrease downtime and optimize the digging strategy of the machine. The training simulator is a TV model system which the trainee controls from simulated cab. Dragline instrumentation is achieved by a computer, a control/display console for their operator and sensors mounted throughout the dragline. The dragline simulation model is a computer program to determine production as a function of overburden properties, dragline specifications and removal strategy. The simulation model used in conjunction with the recorded data from the on board system provides a basis for the evaluation and optimization of dragline operating procedures. The dragline simulator, display and recording system and simulation model were initially developed under contract with the Department of Energy.
