Monitoring muon flux variations besides and on a tunnel-boring machine

Tunnel-boring projects require a considerable amount of planning, well ahead of drilling operations. Despite these precautionary measures, unexpected ground geological features (local density variations, cavities, unstable superficial ground, instabilities induced by the driller) impose real-time adaptations of the drilling operations. The direct relation of muon flux absorption with the density of a given medium, makes muography a promising...
