| Lake Lynn Laboratory |
The Lake Lynn Laboratory (LLL) is located 50 miles southeast of Pittsburgh, PA. It consists of an underground limestone mine and surface quarry area. The underground mine portion is a sophisticated underground facility for conducting large-scale explosion trials and mine fire research. Entries are sized to match those of commercial mines, making them authentic, full-scale test galleries. Other facilities located at LLL are the Hydrostatic Testing Chambers for Mine Seals, the Fire Gallery, the Fire Suppression Facility, and the Explosives Testing Site.
