Netherlands, Structural Health Monitoring related to ancient underground mining activities

In the South of the Netherlands activities of underground mining probably begun already by the Romans. Surely these activities strongly developed during the late middle ages. Since the 16th century, marl has been mined on a large scale by the so-called “block breakers” who sawed out the blocks of limestone. Due to a layer of […]
