| [December 22, 2003 (Volume 68, Number 245)] [Unified Agenda] [Page 73213] Department of Labor (DOL) (Proposed Rule Stage) Mine Safety and Health Administration (MSHA) _______________________________________________________________________ 2084. HIGH-VOLTAGE CONTINUOUS MINING MACHINE STANDARDS FOR UNDERGROUND COAL MINES Priority: Other Significant Legal Authority: 30 USC 811; 30 CFR 957; 30 CFR 961 CFR Citation: 30 CFR 18; 30 CFR 75 Legal Deadline: None Abstract: Our current standards require that high--voltage 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 proposed rule would eliminate the need for a modification to use this equipment, and would establish safety requirements for its use. The proposed rule would also include design approval requirements for high--voltage continuous mining machines operated in face areas of underground coal mines.
