The invention relates to a method for designing a drilling pattern for rock cavity excavation and a software product implementing the method. The drilling pat- tern (9) is created by means of a design program. The drilling pattern defines several starting points (29) of drill holes in a navigation plane (N), end points (30) of the drill holes on the bottom of a round (22) and further the directions and lengths of the drill holes. The face of the round is designed to have a desired shape by determining the locations of the end points for the desired face profile (31). A three- dimensional face profile is entered into the design program, which subsequently places end points to the face profile automatically.
La présente invention concerne un procédé destiné à tracer un schéma de forage pour le percement d'une cavité dans la roche et un produit logiciel de mise en oeuvre correspondant. Le schéma de forage (9) est créé au moyen d'un programme de conception. La configuration de forage définit plusieurs points de départ (29) de forages dans un plan de navigation (N), des points de terminaison (30) des forages sur le fond d'un avancement (22) et en outre les directions et longueurs des forages. La face de l'avancement est conçue pour présenter une forme souhaitée en déterminant les emplacements des points de terminaison pour le profil de face souhaité (31). Un profil de face tridimensionnel est entré dans le programme de conception, qui par la suite place automatiquement des points de terminaison sur le profil de face.
