Abstract

La présente invention a pour objet un boulon d'ancrage (1) conçu pour être utilisé notamment dans une mine souterraine ou dans un tunnel. L'invention porte aussi sur une méthode de renforcement d'un mur ou d'un plafond dans une mine souterraine ou un tunnel. En particulier, l'invention concerne une cheville, par exemple, une cheville Rima ? ou boulon d'ancrage pour veines de charbon. Dans l'une des réalisations, le boulon (1) comprend: un arbre (2) ayant une extrémité (5) filetée destinée à recevoir un écrou, l'autre extrémité (6) présentant plusieurs surfaces (3, 3a, 3b) dont chacune s'étend angulairement et longitudinalement dans le sens de l'axe longitudinal de l'arbre (2) et converge par rapport à l'axe vers la première extrémité (5); et une pluralité de colliers (4, 4a, 4b), associés chacun (4, 4a, 4b) à l'une des surfaces (3, 3a, 3b) et coopérant avec ladite surface de telle manière qu'en cas de mouvement relatif de chaque collier (4, 4a, 4b) par rapport à sa surface associée (3, 3a, 3b) en direction de l'autre extrémité, chaque collier (4, 4a, 4b) s'étend radialement jusqu'à se projeter radialement au-delà de sa surface associée (3, 3a, 3b).
