How can ground mines detect?

One of the greatest threats for today's human race is the existence of more than 100 million ground mines in more than 70 countries, and some sources claim that another 5 million new ones are buried annually. Unpleasant mines are problems for countries that need as much land as possible for agricultural purposes, as well as for innocent civilians who continue to suffer long after conflicts. It is estimated that 26,000 people are killed by ground mines each year, many of which are children playing in the fields. There are a number of ways to detect these devices, from simple metal detectors to advanced sound generators, but so far none of these methods has proved to be 100% effective and the costs of some methods are prohibited.

One of the oldest methods for detecting ground mines is a simple loop metal detector. Trained soldiers sweep a suspicious minefield and use a long detentionPositive signs of buried metal. Any mines found by this method would either be destroyed or marked for the future event. In conjunction with the effort to sweep the mine, strong bulldozers would often be equipped with forward flails or weights designed to fired down. This method was generally used to ensure a safe passage for soldiers, not to clean the entire field. The level of false positive values ​​was also very high because the other metal shrapnel set off the detectors and masked the signature of the real mine. Anti-personnel devices were also primarily made of ceramics or plastic, which were not easily detected by traditional electronic sweepers.

Another way to detect ground mines is the use of trained animals. Dogs can be trained to clean chemical signatures of buried ground mines and signal their human controllers, but such work can be exhausting for animals and dangerous to human disposal teams. OtherThe animals have used in a similar way, including several types of rats. These rats can be trained to pass through the field and signal all positive interventions. These animals are particularly useful because they are too light to launch most devices. The search process can still be very very demanding to work, with estimates of costs taking place from $ 300 to $ 3,000 USD (USD) for a detected mine.

Small robots are also used to detect ground mines, even if it is necessary to specify before they are used on a large scale. These remote -controlled robots are attached to compact metal detectors or radar units penetrating ground ground and sent to suspicious mining fields. The human operator can look for significant electronic signatures, which could mean that the mine is present. The robot releases a marked spray and returns to its staging area. However, creating such a robot is very expensive and identification technology is still not improvedon.

To eliminate the problem of false positives in scientists and metal pollution, they also work on a sound detection system designed to penetrate the Earth and in fact cause the vibration of ground mines. Conventional sound waves generators are not practical for detection purposes, as the amount of sound energy desired would question anyone in this area. Like the laser beam concentrates light energy, the new form of the sound generator would concentrate the sound waves on a specific area and detect the vibrations of all devices buried. The sound would not be audible even a few meters from the device, which would be safe for human use. Safely removing the detected mines would still remain problematic, but at least the number of false positives would be reduced.

One interesting new method for downward detection is still in the experimental phase, but shows a great promise. The form of a leaf plant called the cress has been genetically created to turn red in the presence of chemicals connectedCH with them. The plan to use this modified cress would first include spraying a suspicious minefield with a special fertilizer. The creek seeds would then be dropped to the field and left to grow. Within a few weeks, any exposure to the chemicals contained in the ground mines causes the cress beets to turn red, thereby marking the lcoation down, the modified watercress only in special fertilizer, which would reduce the chances of invasive overgrowth similar to Kudzu. This method would be organic, accurate and economic, as a large area of ​​arable land could be removed by explosives in a much less time than methods are currently being used.
