US Army Engineers Locating Land Mines

 

In Italy with US Army Engineers locating land mines, 1943. The conventional method of mine detection was developed in World War II and has changed little since then. It involves a metal detector, prodding instrument and tripwire feeler. Deminers clear an area of vegetation and then divide it into lanes. A deminer advances along a lane, swinging a metal detector close to the ground. When metal is detected, the deminer prods the object with a stick or stainless steel probe to determine whether it is a mine. If a mine is found, it must be deactivated. Although conventional demining is slow (5–150 square metres cleared per day), it is reliable, so it is still the most commonly used method. Integration with other methods such as explosive sniffing dogs can increase its reliability. Demining is a dangerous occupation. If a mine is prodded too hard or it is not detected, the deminer can suffer injury or death. The large number of false positives from metal detectors can make deminers tired and careless. According to one report, there is one such incident for every 1000–2000 mines cleared. 35 percent of the accidents occur during mine excavation and 24 percent result from missed mines.
