ABSTRACT
Vulcan is one of the few active remaining collieries from Jiu Valley, in the Meridional
Carpathian Mountains. Before proceed with stability analysis was necessary to create a model of waste dump Valea Arsului - Vulcan colliery. The landfill location is in an area affected by the subsidence phenomenon due to underground coal extraction. The challenge was to estimate the actual shape of the terrain surface beneath the waste dump body. As starting point was old aerial photogrammetrical survey made before starting landfill process. The paper presents the modeling approach and the achieved results of subsidence phenomenon occurred in the waste dumping area Valea Arsului - Vulcan.

Keywords: subsidence modeling, mining waste dump, Jiu Valley colliery
