... in controlled rockfall experiments and long-term surveillance tests in various mines and conditions. The cameras can detect rockfall events at less than their resolution as rockfall creates larger craters, impacts, and dust trails visible in the thermal IR. The surveillance test determined that the cameras work...

...), the former Homestake Gold Mine. Multiple cameras, each capable of monitoring a 100 m (350 ft) length of mine drift, have demonstrated a measurement resolution of 0.12 mm (0.005 in)-sufficient for correlating measured vibrations to periodic pumping intervals in a water pipe. The system was then deployed...
