Underground coal mine operators that use high-voltage continuous mining machines are currently following most of the provisions of the final rule through conditions set forth in their granted Petitions for Modification (PFMs).
27-02-2003· raise and improve the voltage regulation at the continuous mining machines which may be located over long cable distances from the mine incoming electrical substation. This is extremely valuable for large underground continuous mining operations that use high power electrical miningHigh Voltage Continuous Miners - Coal Leader,Underground coal mining managers, engineers and equipment specialists recognized long ago the relationship between input voltage and mining rate. Starting in the late 1970s mining machines progressed steadily from 440 volts to 950 volts with a corresponding increase in productivity, and by 1990 virtually all continuous miners were powered with 950 volts.(PDF) Best practices for Continuous Miner Operations,For high voltage machines (1000 VAC or above), no temporary splices are permitted,When moving continuous mining machines around corners, or in other instances where the left .
