A method for designing a drilling plan for rock cavern excavation, which defines in advance for a round to be drilled in a tunnel face at least the locations of drill holes in a predetermined coordinate system, uses 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 and the topography 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. |
