Dragline production is influenced by physical parameters of the operating pit. These parameters include depth, swell of overburden, thickness of coal seam, and stability of materials. Production is further influenced by operating parameters such as width of panel, length of digout, placement of spoils and sequence of digging-spoiling operations. While the physical parameters cannot be changed, it is possible to increase production through the operating procedures, therefore, there is some best combination for a particular dragline. These volumes contain the results from the investigation of single-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. Four operating mines were computer simulated during the study. Results indicate that most operating mines can benefit from computer simulation and subsequent implementation of optimization procedures. The Dragline Simulation Model (DPS) was designed to assist the mining engineer in finding an optimal combination of operating parameters for a given combination of physical parameters. The model simulates the digging, spoiling, walking, deadheading, and maintenance actions of a dragline. It works with a three-dimensional representation of the operating pit to reflect the results of digging and spoiling.
