Diesel Particulate Matter (DPM): Briefing Paper
Diesel-powered vehicles and equipment produce airborne diesel particulate matter (DPM), a recognised carcinogen. Prolonged exposure at high concentrations can affect respiratory and cardiovascular health, making effective management in underground mines an operational priority.

As part of the Innovation for Cleaner, Safer Vehicles initiative, ICMM hosted a three-part knowledge share series in 2025, bringing together member companies, OEMs, and technology suppliers to exchange practical experience, highlight innovations, and discuss emerging approaches. This briefing paper summarises key insights from those sessions to support progress and strengthen collective action.
-
Although a range of emission-control technologies is available, consistent adoption and sustained performance remain challenging. This points to the need for stronger collaboration and shared learning across the industry, particularly as regulatory expectations continue to evolve.
-
A layered approach is central to managing DPM effectively.
-
Monitoring and maintenance form the foundation. When undertaken together, they create a feedback loop in which exposure data informs maintenance strategies and supports reliable equipment performance.
-
- Engineering controls – including filtration, ventilation, and modern engine technologies – are most effective when integrated into a broader management system and backed by disciplined upkeep.
- Electrification offers a longer-term pathway to removing DPM from underground environments. Adoption is increasing, though widespread implementation will take time and rely on coordinated effort across the value chain.
-
Together, these actions can support healthier working environments and contribute to the industry’s wider ambition to advance cleaner, safer mining.
