Interstate Technical Group on Abandoned Underground Mines
5th Biennial Workshop
April 21-23, 2004, Tucson, AZ

The 5th Biennial Workshop offered by the Interstate Technical Group on Abandoned Underground Mines (ITGAUM) will focus on subjects related to the effects of mine development on highway planning, design, construction, maintenance and infrastructure development. Related topics pertaining to sub-structure exploration and geophysical testing, which identify potential hazards associated with abandoned mines will also be addressed and relevant case histories will also be discussed.

This important transportation-related workshop on abandoned underground mines is co-hosted by the Arizona Department of Transportation, the Arizona State Mine Inspectors Office, and the Arizona Geological Survey and co-sponsored by both the Federal Highway Administration and the Transportation Research Board.

Conference Site:
