Title (EN) METHOD OF MINING USING A LASER
(FR) PROCÉDÉ D'EXTRACTION MINIÈRE UTILISANT UN LASER
Abstract:
(EN) A method for mining using a laser to cause spalling includes the steps of generating and delivering a laser beam to a work surface of a geological strata having a sought after mineral to be removed from the stratum; moving the laser beam about three perpendicular axes so that a focal point of the laser beam moves across the working surface and rapidly increases the surface temperature of the working surface; providing a source of a cooling media, and delivering the cooling media to the working surface so as to rapidly cool the working surface subsequent to the rapid surface temperature increase generated by the laser beam so as to effect a fracturing of the working surface and to generate a plurality of chips from the working surface; and removing the chips spalled from the working surface.
(FR) L'invention concerne un procédé d'extraction minière utilisant un laser pour produire un écaillage, qui comprend les étapes consistant à générer et envoyer un faisceau laser sur une surface de travail d'une strate géologique contenant un minéral recherché devant être extrait de la strate; à déplacer le faisceau laser autour de trois axes perpendiculaires de sorte qu'un point focal du faisceau laser se déplace sur la surface de travail et augmente rapidement la température de surface de la surface de travail; à fournir une source d'un milieu de refroidissement, et à distribuer le milieu de refroidissement à la surface de travail de manière à refroidir rapidement la surface de travail suite à l'augmentation de température de surface rapide générée par le faisceau laser de façon à réaliser une fracturation de la surface de travail et à générer une pluralité de copeaux à partir de la surface de travail; et à enlever les copeaux écaillés depuis la surface de travail.
