Abstract

La présente invention concerne un système de boulon d'ancrage de toit de mine, comprenant un élément d'appui, pourvu d'un premier élément, d'un deuxième élément, espacé du premier élément et d'ouvertures, définies à travers chacun des premier et deuxième éléments et d'un boulon d'ancrage de toit de mine, s'étendant à travers les ouvertures. Lorsqu'une charge est appliquée au système de boulon d'ancrage de toit de mine, l'élément d'appui cède ou se déforme. L'invention concerne également un procédé de fourniture d'un support de toit dans une mine souterraine, comprenant la fourniture de l'élément d'appui et l'introduction d'un boulon d'ancrage de toit de mine à travers les ouvertures de l'élément d'appui et dans un trou de forage dans un toit de mine, l'élément d'appui se déformant lors de l'application d'une charge supérieure à une charge prédéterminée.
