  • Computer application in mining
    The current mine design and planning process is largely manual, requiring substantial resources and expertise to generate a single layout, with evaluations typically aiming for one economically feasible solution due to operational constraints. However, the application of computer techniques holds potential to streamline this process by enabling the efficient generation and evaluation of multiple alternative layouts.
  • Role of computer in mining engineering
    Recent advances in computer graphics have facilitated rapid development and evaluation of mine plans, but the lack of software that integrates geological modeling, engineering design, and planning strategies with interactive on-screen graphics capabilities has limited the adoption of multiple planning options. The focus of this study is on creating a fully integrated computer-aided mine planning package to address this gap.
  • Role of computer in mining engineering

    The integrated computer-aided mine planning and design procedure will help to maximize deposits recovery at greatly reduced costs. This procedure would aid the mining engineer to develop a total mine plan from the conceptual design stage, the analysis of bore hole data, and the drafting of a layout to the final working mine plan, mine schedule, simulation and cost evaluation.
