Title (EN) METHOD AND ARRANGEMENT FOR DESIGNING DRILLING PLAN
(FR) PROCÉDÉ ET SYSTÈME POUR PRÉPARER UN PLAN DE CHARGEMENT
Abstract:
(EN) The invention relates to a method and an arrangement for designing a drilling plan (12) for rock cavern excavation. The method defines in advance for a round (26) to be drilled in a tunnel face at least the locations of drill holes (13) in a predetermined coordinate system, using the drilling plan created by means of a computer-assisted design program. The method determines pull-out of a round on the basis of the locations of the hole ends (36) and the topography (28) of the rock remaining after a round blast, and designs or modifies the drilling plan for a subsequent round on the basis of the thus determined pull-out.
(FR) L'invention concerne un procédé et un système utilisés pour concevoir un plan de forage (12) pour le percement de cavités dans la roche. Selon ledit procédé, les emplacements de trous de forage (13) sont définis à l'avance dans un système de coordonnées prédéterminé, au moyen d'un programme de conception assistée par ordinateur, pour une volée (26) à percer dans un front de taille de tunnel. Ledit procédé permet de déterminer le volume de roches excavées sur la base des emplacements des extrémités de trou (36) et la topographie (28) des roches restantes après un coup de mine pour former une volée et de concevoir ou de modifier un plan de chargement pour une volée suivante sur la base du volume de roches excavées ainsi déterminé.
