KGS receives DOD grant to advance tunnel detection technology

LAWRENCE — Noninvasive seismic techniques developed at the Kansas Geological Survey to locate abandoned mines in Kansas also have been used to detect drug runners’ tunnels in the Southwest, clandestine tunnels in war zones and other subsurface structures. To further advance the technology, the KGS has been awarded $2.54 million by the U.S. Department of Defense. […]

Prospectors dug and abandoned hundreds of mine tunnels south of Baxter Springs and under the town of Galena in southeast Kansas in the late 1800s, and lead and zinc mining continued in the area until 1970.

In 2009, the KGS used the same method in Galena as they had near Baxter Springs, along with exploratory drilling, to identify subsidence-susceptible areas beneath city streets. […]
