As awareness of emissions-related health risks grows, mine operators need to know whether diesel particulate matter (DPM) levels in their underground facilities are within safe, legal limits.

Our ventilation engineers have extensive international experience in helping mining operations develop DPM programs for baseline and compliance sampling. We then analyze the results in our state-of-the-art laboratory to determine emission levels at different locations. When the permissible exposure limits are exceeded, our consultants customize emission control strategies to suit the unique requirements and challenges of each underground environment.
