Rescuers continue to dig toward the Utah miners trapped by a cave-in last week, but it is slow work.
Some residents of Huntington, Utah, are now asking questions about the methods used to extract coal from the mine. Miners say the work is dark, dirty and dangerous. They say that 2,000 feet below a mountain, the earth groans.
Some mines practice a method of retrieving coal called retreat mining. The method produces great profits for the owners and plenty of danger for the workers. One of the mine's co-owners says the workers were not engaged in retreat mining, but critics question the safety of the non-union mine where the cave-in took place.
Miners talk about the dangers of their work and what goes on under the ground.
