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.
