Diesel exhaust is a known carcinogen and has been linked to several negative health outcomes, yet it is commonly used in industrial settings such as underground mining. Alternative fuels such as GDiesel® (GD), a natural gas/diesel blend, have the potential to reduce health exposures and associated ...

Diesel equipment exhaust is a primary source of carbon-rich submicron particles in the underground mine atmosphere. In this study, the characterization of the morphological and physical properties of particles was used for identification of emission source and understanding the effect of diesel part...

The introduction of diesel particulate filters (DPF) technology has been an important step towards controlling diesel emission from heavy-duty diesel -powered underground mining vehicles. The Johnson Matthey CRT® (Continuously Regenerating Trap) technology that combines a diesel oxidation catalyst ...

The quantification of exposures to diesel particulate matter (DPM) could be adversely affected by the presence of micron-sized aerosols in DPM samples containing organic and elemental carbon from other than combustion sources. Therefore, size classification plays an important role in the collection ...

Reducing Diesel Particulate Matter has a direct impact on improving air quality and thus workforce health and safety. PT Freeport Indonesia has selected a multi-stage reduction strategy to reduce DPM emissions in its underground operations. This paper provides an update on challenges, success and le...

Experimental sampling of diesel exhaust nanoparticles using a Naneos Partector 2 instrument has been conducted in an underground polymetallic mine. This sampling was conducted within 12 minutes in the operator open cabin of the mine face LHD loader R1700 (engine model Cat@C11 ACERT, 241 kW, Tier 3/S...
