According to the above-mentioned prior art, when the explosive cable is spread on the forest land, the explosive cable is caught on the tree, so that the expansion cannot be performed and the minefield cannot be treated. Become. Also, in terrain with no visibility, such as winding forest roads, it is impossible to bend and extend along the road, and the minefield cannot be treated.

[0004] It is also conceivable that the baggage may be lifted and transported, or the explosive line may be spread by an airship that transports personnel, but in this case, since the airship uses only levitation gas, the balloon portion becomes large. It is difficult to get out of forest areas. In addition, when a small airship is used, the weight of the explosive line is too heavy, making it difficult to tow it.

The object of the present invention is to
Even in unpredictable terrain such as winding forest roads,
It is an object to provide a land mine disposal method that can easily tow and extend to dispose of a mine field, and a land mine disposal device that can easily and reliably implement such land mine disposal.

According to the structure of the first invention described above, the towing device can be miniaturized in order to utilize both the buoyancy of the balloon and the dynamic lift of the propulsion device, and the towing body itself should also have buoyancy. The weight of the towing device can be reduced by reducing the weight of the towing device to zero, and the towing device can be made lighter and more compact. As a result, towing of the towed body can be easily carried out in a forest area, a winding road, or other places where visibility is unclear, and the minefield can be treated accordingly.

Further, according to the structure of the second aspect of the present invention, the balloon of the towing device can be reduced by removing the levitation gas, and the propulsion device removed from the balloon can be folded. Further, the towed body can also be reduced by removing the levitation gas. The balloon, the propulsion device, and the towed body thus separated and reduced can be easily transported to a predetermined place. Then, first, the levitation gas is injected into the balloon of the towing device to expand the balloon, and the propulsion device is attached to the lower portion of the balloon, and the balloon is expanded to a predetermined posture. Next, the towed body is connected to the towed device, and immediately before the towed body is extended, levitation gas is injected into the towed body and expanded.

It can be propelled by the device and can be adjusted in the towing direction. At that time, by operating the remote control device and transmitting the operation command to the control section of the towing device in a wired form via the control cable, the towing by the towing device can be controlled. As a result, the towed body containing the levitation gas can be extended (laid) in a forest area or a winding forest road.
The towed body can then be towed above the ground and can bend in any direction.

After the towed body is extended by the towed device, an operation signal for starting injection is sent from the remote control device to the explosive supply device to inject explosives into the explosive tube group in the towed body. Then, by operating the remote control device, the levitation gas can be gradually discharged from the towed body to reduce the buoyancy, and the towed body can be landed on the ground. After landing, the remote control device can be operated to ignite the ignition device to ignite the explosives to explode the minefield.
