METHOD AND SOFTWARE PRODUCT FOR DESIGNING DRILLING PATTERN FOR ROCK CAVITY EXCAVATION

摘要

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.
