High-Voltage Continuous Mining Machine Standard for Underground Coal Mines
This final rule revises the Mine Safety and Health Administration's (MSHA's) electrical safety standards for the installation, use, and maintenance of high-voltage continuous mining machines in underground coal mines. It also revises MSHA's design requirements for approval of these mining machines. The final rule will allow mine operators to use high-voltage continuous mining machines with enhanced safety protection against fires, explosions, and shock hazards and will facilitate the use of advanced equipment designs.
Coal Mine Dust Sampling Devices
This final rule revises requirements that the Mine Safety and Health Administration (MSHA) and the National Institute for Occupational Safety and Health (NIOSH) use to approve sampling devices that monitor miner exposure to respirable coal mine dust. The final rule updates approval requirements for the existing ``coal mine dust personal sampler unit'' to reflect improvements in this sampler over the past 15 years. The final rule also establishes criteria for approval of a new type of technology, the ``continuous personal dust monitor,'' which is worn by the miner and will report dust exposure levels continuously during the shift.
