| Particulate filter designed to reduce diesel engine emissions |
Background
Currently, a wide range of applications are available to control diesel particulate matter (DPM) emitted from engines in mine vehicles effectively. One effective control option is the use of a diesel particulate filter. Because of the wide variety of function and applicability of the filters, mine operators have found it difficult to select the proper one to use with specific pieces of underground equipment. Factors that include duty cycle, engine exhaust temperature, and limited available volume constraints must be considered when selecting the proper filter. To assist mine operators with this potentially complicated process, NIOSH researchers have developed a "Filter Selection Guide." This handbook is currently available through Internet links on both the NIOSH mining and Mine Safety and Health Administration Websites. The "Filter Selection Guide" walks operators through each step of the selection process and outlines the information necessary to complete each step. At the completion of the guide, operators are provided the best filter options to control DPM emissions.
Potential Outcome
The long-term impact of the "Filter Selection Guide" is that it will provide mine operators with correct guidance for selecting filter-based diesel emission controls and will avoid the unnecessary and costly expense of installing inappropriate controls. Use of this guide will enhance the potential for miners to be better protected from diesel emissions. To obtain more practical knowledge that would be incorporated into the guide, NIOSH is currently working with the Queenstake Mining Co., of Elko, NV, to evaluate the guide’s effectiveness in assisting mine personnel in choosing the appropriate diesel particulate filter for various diesel-powered vehicles used in their operation. This work will add significant real-world input to the guide. The research should be completed in early 2007, and the guide updated with new information by early 2008.
