(FR) BLOC D'APPUI DÉFORMABLE
Abstract:
(EN) A mine roof bolting system including a bearing member having a first member, a second member spaced apart from the first member, and apertures defined through each of the first and second members, and a mine roof bolt extending through the apertures. When a load is applied to the mine roof bolting system, the bearing member yields or deforms. Also, a method for providing a roof support in an underground mine including providing the bearing member and inserting a mine roof bolt through the apertures of the bearing member and into a borehole in a mine roof, wherein the bearing member yields upon application of a load in excess of a predetermined load.
(FR) 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.
