Available in PDF, EPUB and Kindle. Book excerpt: Diesel engine usage in mining operations contributes to high productivity. The downside is the exposure of workers to a mixture of gases and particulate contaminants in the working environment, a concern to occupational health and safety. DPM in the ventilation air is a critical pollutant adversely affecting the health of underground mine workers. DPM is considered a human carcinogen. This thesis presents a new way of characterizing DPM concentration in underground mines by the application of a new numerical modeling technique. The transport of DPM from diesel exhaust emission is modeled using a mine ventilation transport model with calibrated dispersion coefficients. The method focuses on mass balance, starting with the source term of the diesel engine estimated from tailpipe emission concentration and fuel consumption data. The source term is input to the DPM transport model to predict concentrations mine-wide, as well as in production zones. The proposed method is applied to an operating mining example. The model results are presented and compared with field measurement.

This book was released on 2017 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Diesel-powered equipment is a significant component of underground mining operations. Miners' exposure to diesel exhaust is harmful. The standard Diesel Particulate Matter (DPM) monitoring method (NIOSH 5040 method) has limitations that preclude rapid DPM estimation and detailed understanding of DPM variations over time. However, real-time DPM monitors do not inherit these limitations. Biodiesel is often used as a substitute for regular petroleum-diesel because of its ability to emit less DPM. However, accuracy of available real-time DPM monitors has not been determined in mines using 70% to 99% (high-percent) biodiesel. The present research addresses this need by rigorous testing of a commercial real-time DPM monitor against the NIOSH 5040 method in active underground metal mines using high-percent biodiesel. The real-time DPM monitor was used to collect transient DPM data at mines' work faces, in exhaust air and intake air drifts. The extensive amount of data is characterized by use of Frequency Distribution (FD) models. The collected data revels strong variations in local DPM levels and suggests that attention to DPM area concentrations would provide a valuable complement to the miners' personal DPM exposure determinations. The results also highlight the potential importance of monitoring miners' short term DPM exposure. The measured data also revels the significance of DPM recirculation by auxiliary fan and ventilation duct systems. This research uses a 2D CFD model to examine stope ventilation parameters for a dead-end mine entry and identifies improved ventilation practices for efficient ventilation. Lastly, good work practices for the real-time DPM monitor (FLIR Airtec) used in this research are suggested"--Abstract, page iii.

Available in PDF, EPUB and Kindle. Book excerpt: The use of diesel-powered equipment in underground mining operations provides many benefits to the industry. It also presents many challenges to the health and safety of workers as it is a significant source of submicrometer aerosols and noxious gases. This book was developed to assist the coal and metal/nonmetal underground mining industries in their efforts to reduce the exposure of workers to aerosols and gases from diesel-powered equipment. It includes information collected by researchers at the National Institute for Occupational Safety and Health/Office of Mine Safety and Health Research (NIOSH/OMSHR). Prior to the production of this text, the knowledge on this complex issue was fragmented. The goal of this volume is to make the information available in one easy-to-use reference. The book includes comprehensive, mine-specific programs for use by mechanics, mine ventilation engineers, industrial hygienists, mine managers, union health and safety representatives, and personnel responsible for the acquisition of diesel vehicles, engines, exhaust aftertreatment systems, fuels, and lubricants. The description of methods to reduce exposure to diesel aerosols includes curtailment of diesel particulate matter and gaseous emissions at their source, and controlling airborne pollutants with ventilation and personal protective equipment. This information should also help researchers in industry, government, and academia to identify areas that need to be addressed in future research and development efforts.

This book was released on 2015 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
Download or read book Concentrations of Diesel Particulate Matter DPM Within an Underground Mine written by Ashley Neby (R.) and published by . This book was released on 2012 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demands for silica sand are steadily increasing as a result of its usefulness in hydraulic fracturing, a process used to extract natural resources from the earth. As the demand for silica increases, the amount of diesel engines also increases to aid in the mining and processing of silica sand. Diesel Particulate Matter (DPM) is the material exhausted from diesel engines, and is hazardous to human health. The Purpose of this study was to evaluate the concentrations of Diesel Particulate Matter (DPM) within an underground silica sand mining site. This research included industrial hygiene sampling, which was compared against previous concentrations collected by the Mining Safety and Health Administration (MSHA). Samples were gathered utilizing a DPM collection filter, cassette, jeweled impactor, and air-pump; which measured the concentration within the mine. Past samples collected by MSHA have exceeded Permissible Exposure Limits (PEL) enforced by 30CFR57.5060. The sample collected during this research was well below permissible limits. Although the mine was incompliance with federal regulations, further controls are recommended to reduce potential for DPM inhalation.

Available in PDF, EPUB and Kindle. Book excerpt: The exposure of mine workers to diesel particulate matter (DPM) and gases is an issue of great concern to the underground mining community. As industry works to achieve compliance with these standards, mine operators are looking for feasible methods for reducing DPM concentrations in their mines. In addition, the industry needs methods to accurately measure DPM to ensure that the control strategies they adopt are working successfully. The use of dieselpowered equipment by the underground mining community has continuously increased over the last several decades. A similar trend is seen in underground metal/nonmetal mines. This extensive utilization of diesel-powered equipment generates the potential for exposure of underground miners to particulate matter and gaseous emissions from this equipment and creates an important challenge for the mining industry worldwide to control these emissions. In recent years, studies have shown that long-term exposure to combustionrelated fine particulate pollution, including diesel particulate matter (DPM), is an important risk factor for cardiopulmonary and lung cancer mortality. Therefore, health issues associated with exposure to DPM are receiving substantial attention from the public, government agencies, and academia. The book Controlling Exposure - Diesel Emissions in Underground Mines present an overview of the integrated approach and review the strategies being used by mines to reduce the concentrations of DPM emitted from the tailpipe, as well as present results from research evaluating these strategies.
