Electric Motor-Driven Mine Equipment and Accessories and High-Voltage Longwall Equipment Standards for Underground Coal Mines

This document contains two technical corrections to the final rule published in the Federal Register on March 11, 2002 (67 FR 10972). The final rule mandated electrical safety standards for the installation, use, and maintenance of high-voltage longwall mining systems used in underground coal mines. The final rule also included design approval requirements for high-voltage equipment operated in longwall face areas of underground mines. These provisions allow the use of high-voltage longwall face equipment with enhanced safety protection from fire, explosion, and shock hazards. The formula in paragraph 18.53(o)(1) contained two typographical errors. This document corrects those errors.
