Abstract
A method for increasing effectiveness of mine clearance when clearing landmines. A vehicle-mounted, mechanically driven, rotary cultivator type demining tool is provided. The demining tool includes a horizontal shaft, a demining unit rotating around the horizontal shaft, a plurality of parallel demining discs located at a distance from each other and rotating around the shaft which when the demining tool is in operation cut down into an upper ground layer to a pre-determined depth to cause mines in their path to detonate or to fragment into harmless fragments, and impact devices located between the demining discs for working the upper ground layer between the demining discs such that the impact devices impact with the upper ground layer between each pair of demining discs several times per rotation of the demining tool. An upper ground layer where mines may be deployed is worked with the demining tool.
