Abstract

L'invention se rapporte à un procédé de creusement d'un tunnel devant à être percé dans une montagne ou un sous-col. Ce procédé consiste à forer un grand nombre de fentes (2) à intervalles le long d'une ligne (1) dessinée de façon à définir un tunnel à creuser, ainsi que sur la face frontale (4) entourée par la ligne ainsi dessinée (1), puis à forer un grand nombre de trous auxilaires (3) entre ces fentes (2) et à faire éclater le banc rocheux le long des fentes (2) au moyen de ciseaux tronconiques (7) introduits dans ces trous auxiliaires (3) et soumis à percussions. Ainsi, on peut obtenir un éclatement efficace même des parties dures du banc rocheux et on peut réduire le temps de forage par rapport aux procédés classiques, de sorte que la vitesse du perforation du tunnel est considérablement accrue. Cette invention assure une diminution des vibrations et du bruit grâce à de telles techniques comportant le forage des fentes (2) le long d'une ligne définissant une forme désirée pour un trou découpé (9), le forage de trous (10) pour les charges de poudre le long de la ligne (1) dessinée pour la perforation du tunnel, ainsi que sur la surface entourée par la ligne ainsi dessinée (1) et dans les trous découpés (9) en vue de permettre le chargement des trous (10) avec de la poudre explosive ou expansive, ce qui permet de faire éclater le banc rocheux à l'aide de la poudre explosive ou expansive assurant le découpage lequel, peut être effectué efficacement sur une section transversale large par utilisation d'une petite quantité de poudre explosive ou expansive.
