Abstract

Diesel motor emissions cause eye and throat irritation. Several compounds in diesel particulate matter are carcinogenic. In an approach to reduce the risk at source, the authors tested in the laboratory a classical underground loader and an underground loader powered by a hybrid diesel-electric motor. The impact of the use of a ceramic filter on the two vehicles was evaluated. However, the use of the filter on the classical underground loader proved problematic. The results demonstrated significant reductions in particle and gas emissions and therefore in ventilation requirements in the operation of the hybrid vehicle. Although the results are positive, the authors believe that this single study cannot precisely determine the impact of such a technology on the air quality for an entire mine.
