Mine clearance

In the combat zone, the process is referred to as mine clearance. The priority is to breach the minefield quickly to create a safe path for troops or ships. Speed is vital, both for tactical reasons and because units attempting to breach the minefield may be under enemy fire. In this situation, it is accepted that mine clearance will be imperfect and there may be casualties from undiscovered mines. Correspondingly, in mine clearance operations the methods that are applied for detection and removal and are quicker, but not as exact. Those methods include those that detect and remove in a single action, such as mechanical demining, carpet bombing, burning of the land or the use of Bangalore Torpedoes. According to the doctrine of the U.S. and other armies, mine clearance is carried out by combat engineers and demining is carried out by Explosive Ordnance Disposal units.

Humanitarian Demining

In times of relative peace, the process of mine removal is referred to as demining. This is a thorough, time-intensive process that seeks to locate all mines so that the land or sea area may be safely returned to normal use. It is vital that this process is exhaustive. Even if only a small handful of mines remain undiscovered, then demining can actually lead to an increase in civilian mine casualties as local people re-occupy an area they previously avoided in the belief that it has been made safe. In this context demining is one of the tools of mine action. Coordinated by Mine Action Coordination Centers run by the United Nations or a host government, civilian mine clearance agencies are tasked with the demining. In post-conflict areas, minefields are often contaminated with a mixture of explosive remnants of war (ERW) that includes unexploded ordnance as well as landmines. In that context the humanitarian clearance effort is often referred to as battle area clearance. Mine action is a domain within humanitarian aid and development studies concerned with activities which aim to reduce the social, economic and environmental impact of mines and the explosive remnants of war (ERW). ... A Mine Action Coordination Centre is an agency established in a region under the auspices of the United Nations to coordinate the clearing of mines. ... The foundation of the U.N.

It is estimated that US$1 billion per year would be sufficient to completely demine globally, but in 2000, only about US$400 million was donated. It takes one to two million US$ to clear a square kilometer of land in most environments. Often, clearing landmines is a necessary condition before other humanitarian programs can be implemented.[1] A large-scale international effort has been made to test and evaluate existing and new technologies for humanitarian demining, notably by the EU, US, Canadian and Japanese governments and by the Mine Action Centres of affected countries. [1],[2]. The United States dollar is the official currency of the United States. ...


Current detection methods

The main methods used for humanitarian demining on land are manual detection using metal detectors and prodders, detection by specially trained mine detection dogs, and mechanical clearance using armoured vehicles fitted with flails, tiller or similar devices. In many circumstances, the only method that meets the United Nations' requirements for effective humanitarian demining, the International Mine Action Standards, [3] is manual detection and disarmament.[2] While some mines have significant metallic content and are fairly easy to detect with metal detectors, many anti-personnel mines and some anti-tank mines have a very low metal content and are much more challenging to locate. The process is typically slow, expensive, and dangerous, but new technologies may provide effective alternatives.

The first step in manual demining is to scan the area with metal detectors, [4] which are sensitive enough to pick up most mines but which also yield about one thousand false positives for every mine,[2] and cannot detect landmines with very low metal content. Areas where metal is detected are carefully probed to determine if a mine is present, and must continue until the object that set off the metal detector is found. Technologies that improve safety include large, pillow-like pads strapped to the bottoms of shoes that distribute weight and dull the impact of footsteps, as very slight disturbances of the ground can tip off old, unstable, or intentionally sensitive mine triggers.[citation needed] Demining can be safer than construction work if procedures are followed rigorously.[3] Image File history File links Download high-resolution version (1174x474, 240 KB) Copyright © 2005 David Monniaux File links The following pages on the English Wikipedia link to this file (pages on other projects are not listed): Demining ...

Biological detection

Honey Bees

Recent research by the University of Montana has revealed that honey bees can, with minimal training, be used to detect landmines with a far greater accuracy and far higher clearance rate than dogs or rats.[5] The honeybee is a colonial insect that is often maintained, fed, and transported by farmers. ...


Rodents

Recent experiments with the Gambian giant pouched rat have indicated that it has the required sensitivity to smell, can be trained reliably with food-reward incentives, and is typically too small to set off the mines.[6] Binomial name Cricetomys gambianus Waterhouse, 1840 The Gambian pouch rat, Cricetomys gambianus, also known as the African Giant Pouch rat, is a nocturnal pouched rat native to Africa. ...


Additionally, experiments with electrode-guided rats suggest that demining could one day be accomplished by guiding "ratbots" into areas that humans are unable to reach.[7] Electrode-guided rats, popularly but incorrectly called ratbots, remote-controlled rats or roborats, developed in 2002 by Sanjiv Talwar and John Chapin at the State University of New York Downstate Medical Center, is a rat with electrodes implanted in the medial forebrain bundle (MFB) and sensorimotor cortex of its brain. ...


Plants
These plants turn red when exposed to nitrous oxide revealing the location of landmines.

The mustard Arabidopsis thaliana, one of the best studied plants in the world, normally turns red under harsh conditions, but using a combination of natural mutations and genetic manipulation scientists from Danish biotechnology company Aresa Biodetection, created a strain that only changes color in response to the nitrous oxide that leaks from landmines and other explosives. Because nitrous oxide can also be formed by denitrifying bacteria, there is some risk of false positives using this technique, and researchers are attempting to make the plant less sensitive. The plants would aid demining by indicating the presence of mines through color change, and could either be sown from aircraft or by people walking through demined corridors in minefields. As of February 2005, no studies have been conducted with actual landmines, though successful studies have been done in greenhouses. In order to prevent the spread of this genetically modified organism into the wild, the plants have been further modified so that they will only sprout when provided with an external growth factor.[8] Image File history File links Download high resolution version (666x808, 79 KB)Arabidopsis plants that chnage colour when there explosives present in landmines and unexploded ordnance (UXO) in soil. ...

Bacteria

A bacterium has been genetically engineered to fluoresce under ultraviolet light in the presence of TNT. Tests involving spraying such bacteria over a simulated minefield successfully located mines. In the field, this method could allow for searching hundreds of acres in a few hours, which is much faster than other techniques, and could be used on a variety of terrain types. While there are some false positives (especially near plants and water drainage), even three ounces of TNT were detectable using these bacteria. Unfortunately, there is no strain of bacteria capable of detecting RDX, another common explosive, and the bacteria may not be visible under desert conditions. Also, well-constructed munitions that have not had time to corrode may be undetectable using this method.[9] Phyla/Divisions Actinobacteria Aquificae Bacteroidetes/Chlorobi Chlamydiae/Verrucomicrobia Chloroflexi Chrysiogenetes Cyanobacteria Deferribacteres Deinococcus-Thermus Dictyoglomi Fibrobacteres/Acidobacteria Firmicutes Fusobacteria Gemmatimonadetes Nitrospirae Omnibacteria Planctomycetes Proteobacteria Spirochaetes Thermodesulfobacteria Thermomicrobia Thermotogae Bacteria (singular, bacterium) are a major group of living organisms. ...

The system works by subjecting the mine to thermal neutrons while searching for the very rare and high energy gamma photons; these photons will only be observed when an object containing nitrogen is being subjected to the neutron irradiation.[11] One possible neutron source is californium-252 which undergoes spontaneous fission. A better neutron source is to use a sealed tube electrostatic D-T neutron generation tube, this has the advantage that the tritium is much less radiotoxic than the californium so in the event of an accident such as an explosion the nuclear mine detection equipment would pose a smaller threat to humans. This type of explosive detection has been proposed for use in airport security and for the detection of explosives in trucks coming into military bases.[12][13][14] A thermal neutron is a free neutron with a kinetic energy level of ca. ...

Acoustic detection

It is possible to detect land mines by directing sound waves at the area to be demined, which causes the land mines to vibrate, and then using a laser to search for vibrations on the surface by means of the Doppler shift - this technique is termed Scanning Laser Doppler Vibrometry.

Demining

In demining, once an object has been detected it is removed by one of the following methods:

  • Manual disarmament.
  • Remote burning of the explosive. Where possible it is better to burn the explosive without detonation. Diethylene triamine (a close relative of ethylenediamine) reacts with TNT to generate heat. The compound that results from this reaction can then be combusted without detonation.[18] It has been reported that this amine is hypergolic with TNT, Tetryl, Composition B and other TNT based explosives. But it does not react in this way with RDX or PETN-based explosives in the same way. Other nitrogen-containing organic ligands (eg pyridine, diethylamine and pyrole) are known to be hypergolic with TNT.[19]
  • Setting the mine on fire while avoiding high-order detonation. This can be done by cutting holes in the mine without detonating its contents[20]

Pyrroles are components of larger aromatic rings, including the porphyrins of heme, the chlorins and bacteriochlorins of chlorophyll, and the corrin ring of vitamin B12. ...

Mine clearance

Some removal methods that are not applied in humanitarian demining, but are common in mine clearance include:

  • The Bangalore Torpedo that clears a path through a minefield. This can also be done using the Antipersonnel Obstacle Breaching System or Giant Viper, a hose-pipe filled with explosives and carried across a minefield by a rocket.[21]
  • Helicopters dragging a plow to overturn or detonate mines. This has the problem of bringing down the helicopter when the plow snags onto objects such as large rocks, but has been corrected by use of pressure-sensitive plow rakes which release when over-pressured. This does however, affects its effectiveness as mines planted in hard ground or near rocks will not be detonated.

The Antipersonnel Obstacle Breaching System is an explosive line charge system that allows safe breaching through complex antipersonnel obstacles. ... The Giant Viper is a heavy vehicle pulled trailer designed to be deployed in areas containing mines. ... For other uses, see Helicopter (disambiguation). ...

Mechanical assets

Mechanical assets effectively combines mine detection and removal into one operation. These machines are applied in both mine clearance and demining. In demining they can be used to verify land that is not expected to be contaminated or as an extra layer of security after an area has cleared by another method, such as dogs. The machines consist of a special vehicle that is driven through the minefield, deliberately detonating the mines it drives over. These vehicles are designed to withstand the explosions with little damage. Some are operated directly with armour to protect the driver; some are operated under remote control.

  • Mine rollers and mine flails. The roller method originated during World War I and the flail method during World War II but both are still used. Neither system is completely reliable and both will leave undetonated mines, requiring the minefield to be rechecked by another method. Mine flails may only be 80% effective; often good enough for military mine clearance, but well below the 99.6% standard set by the United Nations for humanitarian demining.[2]
  • Mine plows
  • Modified long-armed demining bulldozers is being used in a number of countries. It has the capability to remove vegetation before demining and can withstand antipersonnel and antitank landmines. Its long arm gives it the benefit of reducing damage to the main body, especially the operating seat, and 3.5 inch (9 cm) thick bulletproof glass protects the operator from directional mines.[22][23][24]
