This paper focuses on the causes of gravity movements (landslides) at „Bogutovo Selo and Ugljevik East 1” open pit coal mines. The landslides complicate open pit mine operations, but also pose a danger to individual objects, structures and related infrastructure. Those were the reasons which resulted in the need to perform detailed monitoring of landslides, to register changes in active processes, to establish databases and update, improve and recondition the processes themselves. Three landslides have been located within „Bogutovo Selo and Ugljevik East 1” open pit coal mines. The results obtained from hydrogeological and geomechanical surveys, as well as the data obtained from landslide monitoring, enable us to adequately restore objects, structures, related infrastructure and to stabilize the terrain itself at the open pit coal mine.
