Influence of an Open-Pit Quarry on the Stability of an Under
2019年9月13日Abstract. The Trou Loulou is an old underground soft carbonate quarry located in Eastern Belgium. This shallow depth room-and-pillar quarry was mined out from the 16th century for building stone. Now, it is considered as a cultural heritage. In the same area, an open-pit quarry is currently mining carbonated rocks for cement production.
