Abstract
A method for designing a drilling pattern for rock cavity excavation and a software product implementing the method. The drilling pattern is created by means of a design program. The drilling pattern defines several starting points of drill holes in a navigation plane, end points of the drill holes on the bottom of a round 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. A three-dimensional face profile is entered into the design program, which subsequently places end points to the face profile automatically.
