A case study in surface mining simulation with special reference to the problem of model evaluation

Summary This paper discusses the framework for modelling and analysing the materials handling aspects of a conventional contour mine as related to the smaller to medium-size coal mining companies. Special emphasis is placed on model evaluation. The methodology employed consists of: (a) using the surface geometry of the area to be stripped for developing the equations that are used for analysing the critical factors affecting pit layout, (b) effecting engineering and graphical layout of the mine, (c) collecting — through time studies — and analysing equipment characteristic data, (d) constructing the model, and (e) evaluating the model. The results show that the graphical approach for model construction and evaluation is fast, accurate, and reliable.
