In June 2012, the World Health Organisation (WHO) classified diesel engine particulate matter as carcinogenci (Class 1) to humans; based on evidence that exposure is associated with an increased risk for lung cancer.  This puts diesel particulate matter (DPM) in the same category as silica dust and asbestos.  The classification by the WHO has significant implications for mining, particularly where diesel engines are used in underground confined spaces.  Mitigation approaches include: the use of low emissions engines and source capturing techniques.  Managment of underground ventilation systems can be used as an additional layer of control mitigation.

In this regard AMIRA is currently seeking expressions of interest in a potential proposal that would make use of the combined renowned tracer gas expertise of the ChemCentre and BBE-Snowden’s mine ventilation modelling and design expertise to optimize underground mine ventilation systems, particularly to maintain diesle particulate level below recommended concentrations. For more information please contact Chris Du Plessis [email protected]
