(KSL News) There haven't been any new details in some time about the investigation into the Crandall Canyon mine disaster, but today the federal Mine Safety and Health Administration (MSHA) showed off a prototype of a new system designed to help trapped miners escape.
The simulation begins when a white tent at the end of a tunnel fills with a thick, white smoke. The miners then crawl into the pressurized tunnel and ride what they call a "prime mover" to safety.
The tunnel would provide the miners with a constant supply of breathable air and an isolated and structurally protected escape path.
MSHA says the system is still in its early stages and must go through an approval process before it can be used. It's unclear if the escape tunnel would be feasible in Utah because the mines here are so deep.
