摘要： Extraction from rock formation of blocks of rock that are already of a paralellepiped shape and thus do not require final time consuming finishing operations 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 commercialisation. Equipment in the form of an extractor (1-28) permits the simultaneous formation of the slot and the perforations.
