Dealing with diesel emissions at source. Diesel engines are a valuable power source for underground mining but their emissions can be a disadvantage. These emissions are best dealt with at source through the use of exhaust treatment. The need to reduce particulate engines from mining machines is most pressing, driven by new regulations and an increasing understanding of detrimental health effects of exposure to fine particles.
The best solution for particulate emissions reduction is particulate filters. Platinum-catalysed DPF systems are usually not considered suitable for underground. However, other systems such as the DPFi system have been successfully employed in mining.
