N2 - The production rate of mechanical excavators such as tunnel boring machine (TBM) and roadheader depend on the geotechnical properties of rock, machine specifications and operational parameters. TBMs are being utilized for the construction of various tunnels for the purpose of access, conveyance of ore and waste, drainage, exploration, water supply and diversion in mining and civil projects. To obtain the maximum production with optimum power from any mining or civil operation, the excavator should be chosen carefully depending on the ground condition and mass rock characterization. Examining those rock characteristics, evaluating the geological structures in the field, and choosing the right TBM for excavation are the main geotechnical and technological investigation steps to conduct the project. In this paper, intact rock properties e.g., strength, density, brittleness and mineralogical features of rock, rock mass characteristics such as frequency and orientation of discontinuities are examined and their influence of TBM advancement are highlighted.
