Computer simulation of complex dragline operations

Journal Article


Abstract


  • Large walking draglines are capital intensive pieces of equipment. To maximise the return on investment and to improve the performance of a dragline, its operation and influencing parameters must be understood and fully analysed with the view of optimising the process. Finding the normal working ranges for a given dragline and optimising its operation usually requires that various possible mining scenarios and pit configurations be assessed. This task is normally both difficult and time consuming and requires an analytical solution. This is ideally suited to the application of computer simulation methods. An integrated computer simulation model was developed to assist the mine engineer in planning dragline operations. The model uses a 3D geological modelling system to access the geological database. The model can simulate complex multi seam operations and different digging methods using a developed database. A generalised computer package, DSLX, is used to simulate various dragline digging methods. The software is based on a highly flexible simulation language which uses predefined functions to build strip geometry, working benches, blast profiles and spoil piles. The basic features of the simulation model, the algorithms used in developing dragline pit designs and the results of two case studies are discussed.
