Abstract
Critical factors and research priorities for pollutant interaction and environmental characterization of the use of diesel equipment in underground coal mining are described. Topics examined include factors relevant to the determination of contaminant concentration profiles; interactions of exhaust components in and with mine atmospheres, such as dilution, diffusion, transport, deposition, absorption, and chemical and other physical transformations; factors involved in estimating the exposure of miners to pollutants, inculding ventilation effects, load cycles, mathematical models, and measurements; estimations of concentration ranges for mine atmospheric components and of toxic substances in coal mines if diesels are used; and estimations of exposure to physical agents. Variables considered include engine type and size, fuel type and quality, exhaust control technology, engine loading, duty cycle, and maintenance; as well as mine size, design, and ventilation, and mining techniques.
