In tunnel boring machine (TBM) excavation, cutter maintenance is necessary, but the time for it has to be minimized for efficiency. Although there is extensive literature on TBM cutter wear and predictive maintenance for different industrial applications, there is no optimized policy for cutter changes in TBM tunnelling today. This study aims to investigate the application of reinforcement learning...
In Norwegian drill and blast tunnelling, contracts stipulate collecting Measurement While Drilling (MWD) data from all drillholes. The MWD approach is an objective way of collecting, processing and visualising advance drilling data that have been successfully used in making face decisions for many years in Norwegian tunnelling. MWD data collection consists of equipping drill rigs with sensors recording...
