.... However, because of its higher costs, it is important to use ID drilling in rock formations where it is strictly required. For that reason, this paper aims to develop an Artificial Neural Network (ANN) model in which rock properties and acoustic emission (AE) parameters are considered as main inputs...

... the main factor for performance and excavation costs in TBM hard rock tunnelling. In the NTNU prediction model for hard rock TBMs, the penetration rate depends on the intact rock properties, rock mass properties and the machine parameters. The fracturing factor (k s ) is a rock mass model published...
