Abstract

Rock characterization visualization technique is used for determining the rock mass prediction in underground tunneling. Drilling the boreholes in tunnels to identify and figure out the roof rock specifications is indispensable to create 3D maps and also designing the 3D rock layers. After gathering the information of borehole coordinates, designing, modeling and investigation of the boreholes in roof of tunnels needs to be well organized. The inaccurate estimation of rock mass layers at the roof of tunnels can cause needing more time to schedule and affect economical costs in time. In contradistinction of gathering data of boreholes on the top of tunnels, data belonging the boreholes is obtained by using rock bolters in roof characterization. Generally, the lengths, diameter and spacing between boreholes are standard and easy to get the information about rock masses in 3D. Mapping and designing the 3D model of boreholes and rock structurestogether help us to see the cracks and also gives us the dispersion of different zones in roof. In this study, 3D rock characterization of visualization for underground tunnels was modeled based on possible dataset.
