Abstract

"Diesel Particulate Matter (DPM) is a complex mixture of diesel exhaust gas that consists of carbon, ash, metallic abrasion particles, sulfates and silicates. The diesel soot particle includes a solid core made of elemental carbon, and organic carbon compound attached to the surface of the soot particle. The main source of DPM is diesel exhaust gas. The National Institute for Occupational Safety and Health (NIOSH) and the Environmental Protection Agency (EPA) have determined that DPM is the source of most of the emissions of carbon monoxide, carbon dioxide, oxide of nitrogen, and hydrocarbons in underground coal, metal and non metal mines. It has become a significant health issue, particularly in underground mines where diesel engines are more active in confined areas. The studies have shown that exposure to DPM is the main risk for lung cancer and other lung diseases. Providing an accurate underground ventilation plan can help to dilute the concentration of emissions. Diesel particulate matter should be monitored constantly to ensure it does not exceed MSHA's emission standards. This paper will show the behavior of diesel exhaust emission under the influence of exhaust fan with different speeds, and how the DPM can be detected by using a real time personal sampler. The experiment was conducted in the experimental mine at Missouri University of Science and Technology (MS&T). It is shown that there is a variance of the concentration of elemental carbon depending on the type of diesel source and the speed of exhaust fan. Understanding the relationship between the source and the ventilation system can give a better understanding of what ventilation plan is appropriate to keep the emission concentration as low as possible while taking into account the other affecting factors such as leakage. Some of the tests have not shown a good dilution of the gas but they can suggest other factors to be used for a high probability of reducing emissions. These other factors are recommended in this paper for more research"--Abstract, page iii.
