dc.description.abstract | Résumé La qualité de la fragmentation des roches à l’explosif demeure une priorité et son amélioration continue est recherchée continuellement car elle influe grandement sur les indicateurs techniques et économiques des processus d'extraction. Notre travail a pour objectif de proposer et d’élaborer un plan de tir qui tiendrait compte d’un trou du diamètre 110 mm calculé selon les conditions spécifiques géo-minières de la Mine de BOUKHADRA et incliné de 15° au lieu de 5° à10° utilisé actuellement pour ce, il a été fait appel à la méthode de Langefors. Vu la difficulté de valider le plan de tir obtenu par la méthode de Langefors sur terrain, nous avions proposé le modèle de Kuz-Ram comme un outil de validation Mots-clés: plans de tir, Langefors, mine, kuz-Ram. Abstract The quality of rock fragmentation with explosives remains a priority, and its continuous improvement is constantly sought after as it greatly influences the technical and economic indicators of the extraction processes. Our work aims to propose and develop a blasting plan that takes into account a 110 mm diameter hole calculated according to the specific geo-mining conditions of the Boukhadra Mine, inclined at 15° instead of the 5° to 10° currently used for this purpose. The Langefors method was used for this. Due to the difficulty of validating the blasting plan obtained by the Langefors method on site, we proposed the Kuz-Ram model as a validation tool.
