Resumen Description of a highly explosion-proof lighting system for use in the mechanised mining of narrow seams of coal. A stabilised direct-current power supply feeds a series of converters spaced along the seam. The power supply includes circuitry for protection against short circuits and ground faults. The converters provide power at 8V and 20-44kHz to fluorescent bulbs mounted on the roof supports. Each converter can supply 10 bulbs. The system provides 5lx at the working face as required by standards, with a spacing between bulbs of no more than 3m.
