Provo • Officials say they'll be sealing a 1,200-foot-deep mine shaft where several Brigham Young University students were burned earlier this month playing with homemade gasoline bombs.

Al McKee of Ophir Minerals & Aggregate Group tells the Daily Herald of Provo his company plans to start collapsing and burying the hole this week.

McKee says the site is now under 24-hour surveillance.

Six college students were treated for burns after they reportedly spilled a cooler of fuel into the abandoned mine shaft July 16 and it caught fire.

The shaft is in a remote area of Utah about 80 miles south of Salt Lake City.
