  • Patent number: 7182011
    Abstract: The invention relates to the field of land mines and in particular to devices and techniques for neutralising and/or retrieving land mines. Existing mine retrieval/neutralisation techniques include mechanical excavation or shaped charge attack and such techniques are either susceptible to blast damage in the event of inadvertent mine explosion or can produce ambiguous results (i.e. an operator can be unsure as to whether a mine has been successfully attacked or a non-mine target has been attacked in error). The present invention provides a mine retrieval technique that involves spearing the mine for later retrieval to the surface.
