The objective of this work is to investigate the influence of smoke movement during mine fires on miner evacuation behaviors. A three-dimensional computational fluid dynamics method was conducted to reconstruct the laneway conveyor belt fire scenes under two ventilating conditions. The parameters, including temperature–time histories, …

In ore and mineral mines, underground escape routes are often long and steep. Here, the key priority is to stay calm, find a safe refuge – for instance in a refuge chamber – and wait for rescue team organized at the surface. This is illustrated in exemplary form by escape plans for mines rescue, like those from South African gold mines. D ...

1. Mine fire disasters and evacuation challenges. Mine fires have been a leading historical cause of mass fatalities in the mining industry (Stewart, 2021, Tang et al., 2021).They pose a serious threat to underground mine workers, and efforts to eliminate the potential of fires in a mining environment are still far from realization.
