Nicholas Priznar, a transportation engineering geologist with the Arizona DOT, describes his experience participating in ITGAUM as "eye opening." Priznar points out that although States in the West have different rock types and generally smaller population densities concentrated near mining areas, the techniques for dealing with abandoned underground mines are the same as those in the East.
Participating in ITGAUM helps civil engineers become familiar with mining techniques that might have an impact on civil engineering designs.
In addition, ITGAUM agreed to work more closely with other mine-related agencies and companies with experience using the same methods of monitoring, investigation, and remediation.
That's why we became involved with ITGAUM. By keeping in touch and networking with States with more pressing needs for research and remediation, we hope to glean some insight into our own situation even though our needs today may be modest."
The TRB subcommittee, ITGAUM, and FHWA jointly are pursuing several initiatives, including evaluating subsurface investigation methods, developing a manual of best practices, and refining modeling techniques for mine collapses.
