Abstract

One of the largest mining waste deposits in Romania is in the Montru valley where coal has been exploited for many years. The waste embankment is 60 m high and covers an area of 6 km2 . In March 2000 a large landslip occurred with lateral movement in the order of 30 to 50 m which resulted in the blocking of the River Montru. The slip surface extended downwards into the Pliocene deposits beneath the river floor. The paper describes the investigations undertaken to assess the short and long term stabilty of the waste embankment.

Résumé

L’un des plus grands terrils miniers de Roumanie se trouve dans la vallée de Montru où le charbon est exploité depuis de nombreuses années. Le terril a 60 m de hauteur et couvre une surface de 6 km2. En mars 2000 un important glissement s’est déclenché, avec un mouvement latéral de 30 à 50 m qui a conduit à l’obstruction de la rivière Montru. La surface de glissement se développait en profondeur dans les dépôts pliocènes sous le lit de la rivière. L’article décrit les travaux entrepris pour évaluer la stabilité à court et long terme du terril minier.
