Accurate measurements of tailpipe emissions are becoming an essential part of a good maintenance program for underground mines that use diesel-powered vehicles. Past studies of particulates in U.S. underground coal mines have shown that SPM alone may be present at concentrations greater than 1 milligram per cubic meter (mg/m3), half the 2-mg/m3. Additional Physical Format: Print version: Carlson, David H. Apparatus for measuring diesel tailpipe emissions in underground mines. Washington, D.C.: U.S. Dept. of. The U.S. Bureau of Mines and Michigan Technological University (MTU) are collaborating to develop an apparatus for measuring diesel tailpipe emissions in underground mines. A tailpipe emissions measurement apparatus (EMA) is described that dilutes diesel exhaust and measures the concentrations of diesel particulate matter (DPM), CO, CO, NO, and. Diesel Exhaust Measurement The Dräger EME is an electronic multigas instrument with internal sampling pump. It precisely determines the CO and NOx content in undiluted exhaust gases of Diesel engines. The internal ambient pressure sensor allows the immediate use without preceding calibration in underground mines.
Diesel emission management in underground coal mines 1 PURPOSE OF DOCUMENT Diesel engine powered vehicles are widely utilised in underground coal mines and the engine exhaust emissions must be effectively managed to minimise the risk to coal mine . Diesel Detective to the full-scale dilution tunnel test and concluded that the Diesel Detective is suitable for measuring DPM from raw diesel exhaust. The PRL tailpipe monitor system described in this work was developed through a cooperative research and development agreement between SKC, Inc. (Eighty Four, PA, USA), and the NIOSH/PRL. The. 1. Introduction. Diesel-powered vehicles have been one of the primary sources of nano (D 50 in underground mines,,,,.The physical and chemical properties of these aerosols are a function of numerous factors, including fuel and lubricating oil properties, engine design, engine operating conditions, and exhaust aftertreatment. In the United States approximately 3, pieces of diesel equipment were being operated in underground coal mines by and over 4, units were operated in underground metal/non-metal mines by (Brune, ). Diesel is used primarily in the underground.
Diesel Fuel MSHA § requires diesel fuel with a sulfur content of less than percent ( ppm) EPA requirement for on-highway diesel fuel to be at percent (15 ppm) sulfur by mid – EPA requirement for non-road diesel fuel to be at percent (15 ppm) sulfur by Examples of good working practices for controlling the engine exhaust emissions from diesel powered vehicles such as fork-lift trucks, railway locomotives, buses and lorries, and where there is likely to be an accumulation of diesel exhaust such as in warehouses, locomotive depots, bus garages, vehicle testing sites, fire stations etc. are. exposure to diesel exhaust emissions in underground coal mines. These assessments commenced in October and to date have been completed at five mines. A targeted assessment is an in-depth look at the control measures for worker exposure to diesel exhaust emissions and their implementation. A Sudbury-based mining equipment supply company has launched a unique user case study to measure the effectiveness of HydraGEN™ Technology underground by measuring the changes in emissions and fuel economy on mobile diesel equipment in a Northern Ontario mine. Total Equipment Services Inc. (TES) of Chelmsford has installed a HydraGEN™ unit.
