Abstract:
Respirable silica dust in coal dust poses a significant health risk to miners in underground mines. This study evaluates the filtration efficiency of electrospun reduced graphene oxide (rGO)-incorporated PAN nanofibrous filters with different concentration of rGO (0%, 2%, 6%, and 10% rGO). Using electrospinning, these filters were tested against respirable silica dust and coal dust particles (0.3 -10 μm) at different size ranges. A particle counter assessed filtration performance, while a dry dust aerosol generator (3410U) dispersed particles at 1-6 bar. Results show that PAN and rGO-PAN filters are similarly effective in capturing RC dust and coal dust across flow rates of 30, 50, and 80 lpm. Notably, efficiency improved at 50 lpm for both dust types. These findings highlight the potential of these filters to mitigate respirable silica exposure in underground mining environments.
