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 ...
Efficient evacuation route planning during underground coal mine fires is essential to minimize casualties. This study addresses current shortcomings by proposing a real-time method that integrates a multifactor coupling analysis and the optimized multilayer perceptron regressor-shortest path faster algorithm (MSPFA).
