Optimal Multiple Seam Dragline Operating Procedures. Volume 2: Appendices

摘要

The Dragline simulation model was designed to assist the mining engineer in finding an optimal combination of operating parameters for a given combination of physical parameters. This computer simulates the digging, spoiling, walking, deadheading, and maintenance actions of a dragline and the removal of partings and interburdens by auxiliary equipment. It works with a three-dimensional representation of the operating pit to reflect the results of digging and spoiling. These volumes contain the results from the investigation of multiple-seam coal mining using draglines. Three different coal mining regions of the United States were visited to obtain data and provide examples of typical mining operations. Two operating mines were computer simulated during the study to validate the computer model and gain experience in the program's operation. Results indicate that most operating mines can benefit from computer simulation and subsequent implementation of computer-tested optimization procedures.
