Jumbo at 1300 feet undergorund

Locality: Annabel Lee mine, Harris Creek Sub-District, Illinois - Kentucky Fluorspar District, Hardin Co., Illinois, USA

Perhaps the noisiest place on earth was where this picture was taken. Drilling 1,300 feet beneath the surface in the face of the north orebody in the Annabel Lee mine, this image shows the "jumbo" with 2 rotary drills. The noise level was probably about 150 decibels! We didn't stay very long! Photo by Chris Anderson, May 1987.
