PROBLEM TO BE SOLVED: To permit the detection of a land mine, buried under the ground, safely and exploding the same by a method wherein an unmanned movable device main body is provided with a plurality of gas ejecting ports while compressed gas is ejected out of the ejecting ports by a gas ejecting means against the surface of the ground. SOLUTION: Arms 1A2,... are extended symmetrically into four directions from the bottom unit of a radio-controlled wireless steerable helicopter 1a for spraying agricultural chemicals while a gas ejecting ports 31, 32, a compressor 2 and a gas ejecting means 4 are respectively arranged on the tip end of respective arms 1A2. Compressed gas A, compressed by the air compressor 2, is ejected against the surface of the ground from the gas ejecting means 4 to detect and explode a land mine, buried under the ground, utilizing shock upon colliding the ejected compressed gas against the surface of the ground. The gas ejecting means 4 is constituted so as to be capable of ejecting the compressed gas under a pulse state preferably to eject the sub pulse of the compressed gas so as to restrain the diffusion of dispersed matters after the explosion of the land mine. |
