A framework for realistic microscopic modelling of surface mining transportation systems

Abstract

This article presents a recently developed realistic microscopic simulator for surface mining transportation systems called Surface Mining Transportation Simulator (SuMiTSim). In the road transport sector recent researches proved that for proper deployment of Intelligent Transportation Systems (ITS), the use of microscopic simulation models rather than the conventional macroscopic ones is critical. Microscopic simulators emulate realistically the dynamic traffic on a road network. A conceptual framework for the development of a surface mining micro-simulator is then proposed. The implementation of this framework led to SuMiTSim which is a robust tool for truck traffic analysis and control. Two case studies have been conducted. The results obtained from the first case study show clearly the benefits that can be derived when using SuMiTSim as a laboratory for more efficient haul roads design. The second finding concerns the integration of SuMiTSim as a proactive updater for real-time allocation. Other potential uses of SuMiTSim are highlighted, such as for sound environmental management through controlling fuel consumption and reducing truck bunching effects on mine networks.
