Diesel engines are a major contributor to concentrations of submicron aerosols, CO, CO 2, NO X, SO 2 and hydrocarbons (HC) in underground coal and metal/nonmetal mines. The extensive use of diesel-powered equipment in underground mines makes it challenging to control workers' exposure to submicron aerosols and noxious gases emitted by those ...
Dec 10, 2020· Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Mining regulators and mine operators actively seek practical measures to reduce human exposure to diesel particulate matter via engine testing. Targeted engine maintenance can drastically reduce diesel engine emissions, but workshop employees must have the tools to reliably identify high emitters and to validate the effectiveness of emissions ...
Jun 27, 2018· As part of its day-to-day operations, Olympic Dam relies on a team of approximately 800 underground employees and uses diesel equipment for development, production, ore handling and mine services. While they may look similar to a traditional Land Cruiser or ute, our LEVs are at the heart of our work on low emissions technology.
Underground mining risks. As most mines use diesel vehicles and equipment, workers may be potentially exposed to diesel exhaust fumes in areas such as: underground parts of a mine; where multiple vehicles are used in a single air split; confined areas; enclosed environments; where ventilation is limited or where there is mechanical ventilation
Federal enforcement agency responsible for the health and safety of the nation's miners. MSHA - Compliance Guide for MSHA's Regulations on Diesel-Powered Equipment Used in Undergound Coal Mines : Cover Page
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 workers' short and long term health.
