Abstract: Our current standards require that high-voltage equipment and transformers be kept at least 150 feet from coal extraction areas in underground coal mines. These requirements are intended to eliminate an ignition source for methane and coal dust in close proximity to the work area. The use of new mining technology, in the form of high- voltage continuous mining machines, is becoming more widespread in the mining industry. This equipment uses high-voltage electrical equipment and associated cables. Mine operators, however, must apply to MSHA for a petition for modification from the existing standards if they want to use this high-voltage equipment. The rule will eliminate the need for a modification to use this equipment, and will establish safety requirements for its use. The rule will also include design approval requirements for high-voltage continuous mining machines operated in face areas of underground coal mines.
