A coal mine owner in Utah today said he is hurt by critics who say he ran an unsafe mine and was not doing enough to find six missing miners trapped deep underground.

A narrow hole being drilled in the side of a Utah mountain holds perhaps the last, best chance of finding six coal miners trapped for more than two weeks in a cave-in.

Relatives of six miners trapped in a cave-in accused US officials of giving up on the rescue effort and leaving the men for dead.
