COAL MINE FATALITY - On Sunday April 7, 1996, a mine superintendent
and a miner were located inside of a surface high voltage substation. The high voltage
mine power had developed a fault in the cable which supplied power underground. This
caused the oil circuit breaker to trip inside the substation. The superintendent closed
the 7200 VAC oil circuit breaker several times, but it continued to trip. During his
final attempt at closing the circuit breaker, it exploded. The superintendent and the
miner were seriously burned. On April 18, (11 days later), the superintendent died as
a result of those burns.
This is the 14th coal mine fatality in 1996. As of April 7 last year, there had been
8 fatalities. This death is the first classified as ELECTRICAL in 1996.
