Description
Gaini Jia and co-authors simulated noise in mechanized coal mines in two thousand twenty-five. Noise at the coal face endangers miners' hearing and safety. Equipment and pipelines block the tunnels as obstacles. Those obstacles bend noise paths in complex ways. The team modeled mid and high frequency noise spread. Two simulation methods were combined for accuracy.
Field measurements in test roadways validated the models. Obstacle traits were then varied one by one. Blockage rate, shape, count, and spacing were tested. Some traits mattered surprisingly little to noise levels. Others shaped where noise pooled dangerously. The results target protection where it counts most. Mine designers can place gear to spare workers' ears.
