Three people died in accident at Indiana mine

CNN was reporting this just minutes ago. Apparently it was not miners that were killed, rather it was contractors who were replacing an airshaft at the face of the mine. The accident happened at 11 a.m. this morning and are working on retrieving the
bodies.

No foul play is expected and no explosion was involved.

"The mine is operated by Gibson County Coal. Princeton is located in southwestern Indiana north of Evansville."

Seems like there have been a lot of these sorts of accidents over the summer. Such a dangerous job.
