1812. HIGH-VOLTAGE CONTINUOUS MINING MACHINE STANDARD FOR UNDERGROUND COAL MINES

Priority: Other Significant

Legal Authority: 30 USC 811; 30 USC 957; 30 USC 961

CFR Citation: 30 CFR 18; 30 CFR 75

Legal Deadline: None

Abstract: Our July 16, 2004, NPRM (69 FR 42812) proposed to establish design requirements for approval of high-voltage continuous mining machines operating where miners work in underground coal mines. The rule also proposed to establish new mandatory electrical safety standards for the installation, use, and maintenance of the high- voltage continuous mining machines. MSHA published a supplemental NPRM on March 28, 2006 (71 FR 15359). This supplemental NPRM proposed and requested comments on two issues that arose from oral and written comments that MSHA received during the hearing and post-hearing comment period on the NPRM. These issues involved: (1) Types of trailing cables that can be used with high-voltage continuous mining machines; and (2) a requirement to use high-voltage insulating gloves or other personal protective equipment when handling energized high-voltage trailing cables. MSHA regularly receives petitions for modifications from coal mine operators seeking permission to use high-voltage continuous mining machines. MSHA believes that, with appropriate safeguards, such machines are safe for use and are routinely granted in these petitions.
