  • Process for preparing the exposed surface of a rock formation to permit the extraction of parallelepiped shaped blocks of rock ready for final processing, and process and extractor for extracting such blocks
    Patent number: 6102483
    Abstract: The present invention refers to the extraction from rock formations of blocks of rock that are already of a paralellepiped shape and thus do not require final time consuming finishing operations. The process of the invention involves cutting a long slot in the formation beneath a slice of rock to be removed and then drilling various orthogonal series of parallel aligned perforations to define cutting surfaces that are separated using metal plugs applied to the perforations. In this manner parallelepiped shaped small blocks are obtained directly and can be removed from the formation in a stage virtually ready for commercialization. Equipment in the form of an extractor is also described which permits the simultaneous formation of the slot and the perforations.
