Abstract

L'invention porte sur une cheville d'ancrage pour mine destinée à un trou de mine cimenté de toit de mine. La cheville comprend un élément allongé dont le diamètre transversal est inférieur à celui du trou de mine, une première extrémité et une seconde extrémité. L'élément allongé comporte des déformations de sorte que la tension axiale exercée sur la cheville génère un mouvement axial entre l'élément allongé et le coulis et crée une compression confinée du coulis entre le trou de mine et la surface de l'élément allongé afin de faciliter l'ancrage de ce dernier avec le coulis dans la roche de la mine dans laquelle est formé le trou de mine. La cheville comprend également un rebord situé à côté de la seconde extrémité. L'invention porte également sur un procédé visant à supporter un toit de mine et sur un procédé de fabrication d'une cheville de toit de mine.
