Mine clearance fact sheet

Mine clearance is the process of removing mines from the field. There are two types of mine clearance—humanitarian and military. There are also many steps involved in process and different ways to clear the mines—by hand, using dogs, and machines.

WHAT IS MINE CLEARANCE?

Humanitarian mine clearance is done by mine action workers or local governments. This process is also called demining and is done by deminers. Humanitarian mine clearance removes landmines so people can carry on with lives without stepping on a mine. Then residents can safely do things like going to the market, collect firewood and water, farm and travel to the hospital. Or, they can finally return home, if the mines have kept them away. Humanitarian mine clearance must be very thorough, not leaving any mines behind.

Military mine clearance is done by soldiers, during times of war and armed conflicts. Militaries clear mines so their troops can pass through mines areas. In those instances, their objective is not to clear or mark all dangerous areas.

Before mines can be cleared, there are a number of steps to be done. These include surveying, mapping, and marking the fields.

There are a number of methods used to clear the mines. Clearance is done by hand, with help from dogs, and using machines.

WHAT ARE DEMINERS?


People who clear landmines are called deminers or as some say, “sappers.” Many deminers are former soldiers that come from mined areas around the world. When wars end and the soldiers are not needed anymore, some of them join mine clearance organizations and are trained in humanitarian mine clearance.

Deminers do very difficult and dangerous work. Even though this work is dangerous, many women and men become deminers because they want to contribute to peace and development in their country. With good training they can clear mines and make their countries safer for their fellow citizens.

HOW DO DEMINERS KNOW WHERE TO FIND LANDMINES?

Many times people do not know where mines are located, or warning signs have not been posted. Sometimes mine tape, crossed sticks, painted rocks and other symbols mark off minefields. Landmine survey teams travel around searching for such markings and talk to the local communities and sometimes even the military to find out where the mines are located.

They use maps if they are available, records of where mine explosions occurred, and details about where fighting took place. Too often, minefields are not mapped at all. Sometimes maps exist but are then lost or become obsolete when, for example, mines shift in the ground during heavy rains and become difficult to find.

WHAT ARE THE STEPS IN MINE CLEARANCE?

Surveying the area. This is required before actual clearance can begin. Surveying involves researching and collecting information about the locations of mines in a particular area. To gather this information, records are reviewed (where they exist), and interviews are conducted with victims, local residents, and former soldiers.

Making Maps. Before maps can be drawn technical surveys must be completed. Maps of the mines are then drawn to help deminers locate landmines and mark them for clearance.


Marking the Minefields
. Marking is carried out when a mined area is identified, but clearance operations cannot take place immediately. Specially trained people locate and mark the outer boundaries or limits of a mined area. This is done so people won’t accidentally enter the minefield, and to prepare the area so deminers know where to work. Often people think a whole road or field is mined and will not use the land. But once deminers take a close look and mark the minefields, they can determine if some areas are safe. They mark off only the unsafe areas, and then people can use some of the “safe” land again.

WHAT ARE THE METHODS OF MINE CLEARANCE?

Manual clearance relies on trained deminers using metal detectors and long thin prodders to locate the mines, which are then destroyed by controlled explosions once they are located.

Mine detection dogs detect the presence of explosives in the ground by smell.

Mechanical clearance uses machinery, including vegetation cutters and excavators, which is often attached to bulldozers. These machines can only be used when the ground is suitable, and are expensive to operate. In most situations they are also not 100% reliable, and the work needs to be checked.
Advances in technology have been made in recent years, both in mine detection systems and in mechanical means for destroying mines. However, most of the time, manual clearance remains the preferred method, because it costs less and is more reliable.

DOES THE UNITED NATIONS CLEAR MINES?

The UN organizations involved in mine action do not carry out mine clearance directly. In most countries they advise and assist the national authorities, or a UN peacekeeping mission to carry out mine clearance.

The UN typically establishes a Mine Action Authority or Coordination Centre responsible for overseeing clearance activities. The actual clearance operations may then be carried out by national civilian agencies, military units that agree to take part in humanitarian operations, national or international NGOs or commercial companies.
