OFR-33(6)-79 Application Of A Total System Surface Mine Simulator To Coal Stripping - Volume VI - An Application To A Modified Contour-Area Mine

In this report, the application of the Open Pit Materials Handling Simulator (OPMHS) to a mine located in Ohio using a large stripping dragline, and truck and front-end loader (FEL) is described. The specific objective of the study is to demonstrate the application of the simulator to mine planning and coal production. On the basis of the simulations, it was concluded that the production from the haulback operation should be increased to accommodate improvements in both the stripping dragline's availability and mean cycle time. Several alternatives were studied for the best use of equipment if the present operating parameters could not be improved upon. No economic analysis of these proposals were made.
