Abstract

La presente invenzione si riferisce ad un dispositivo per rilevamento della distanza e dell'orientazione (ubicazione) di un secondo foro rispetto ad un primo di riferimento e ad un modo per il rilevamento degli stessi e per la intersezione di detti due fori, caratterizzati dal fatto di comprendere primi mezzi di emissione di un campo elettromagnetico introdotti in detto primo foro, e secondi mezzi di ricezione di detto campo elettromagnetico introdotti in detto secondo foro. Questa tecnica trova particolare applicazione nel taglio della roccia, per esempio della roccia marmorea o granitica.The present invention relates to a device for detecting the distance and orientation (location) of a second hole with respect to a first reference and a way for detecting them and for the intersection of said two holes, characterized by the fact comprising first electromagnetic field emission means introduced into said first hole, and second electromagnetic field reception means introduced into said second hole. This technique finds particular application in rock cutting, for example of marble or granite rock.
