A Review of Computer Simulations in Underground and Open-Pit Mining

Abstract

The article presents the role of computer simulations in present times and discusses aims and benefits of using such solutions. It was established that by conducting simulations and building virtual models it is possible to increase the efficiency of analysed processes while minimizing the costs of production, logistics, storage, etc. What is more, simulation models allow for scenario analysis of various solutions, and thus making the appropriate decisions based on the obtained results. Therefore, they become the basis for the analysis of various technological and process changes. Simulation and modelling tools are increasingly used in the mining industry. Computer models of mining processes supplied with real data are a useful tool for testing planned changes, an investment risk analysis or a quality assessment of accepted solutions. The authors cited and discussed selected simulations of mining processes made in various tools, and also proposed a method of simulation the process of coal production with a longwall complex in the 3D dimension using FlexSim Simulation Software. The simulation model was built on the basis of the ProcessFlow technology, allowing for building the logic of the system in the form of block diagrams, and thus significantly shorten the time of modelling extensive processes.
