MODELLING OF UNDERGROUND WORKSITE

A method includes the steps of receiving a three-dimensional input model of an underground tunnel system of a worksite, determining an initial first location in the input model for a virtual probe, determining distances between the first location and tunnel walls on the basis of the input model; determining tunnel heading on the basis of processing the determined distances, relocating the virtual probe at a second location in the input model along with the determined tunnel heading, and generating a logical tunnel model indicative of path of the virtual probe travelling in the input model, on the basis of determined locations of the virtual probe being relocated in the input model.
