ABSTRACT

Centuries-long exploitation of rock salt from Tuzla salt deposit has produced significant
deformation of the ground surface and buildings in the town of Tuzla. The southern
edge of the deposit dips beneath the northern part of the town. Although relatively small
size, the deposit represents an extremely complex geological body
The slow, natural processes of dissolution of the deposit’s eastern part were accelerated
by industrial exploitation of saline water (brine) that lasted over 100 years. Exploitation
of the western part of the deposit started much later in 1967, by classical dry
underground mining.
Natural processes and applied exploitation works endangered part of the town above the
deposit. Subsidence has reached its peak in 70-s of the last century, when the city lost
huge number of its residential, commercial and cultural facilities. Although the salt
exploitation ended (2004 and 2007) very complex processes of degradation of wider
deposit environment and urban areas are still ongoing, with visible consequences on the
ground surface.
Featured are the geodynamic phenomena and deformation caused by a complex
structural-tectonic structure of the terrain. Analyzed were also geodetic monitoring data
for the period 1956-2010 which present important information about the processes of
ground surface movements.
Deformation on the ground surface is being developed under the influence of various
factors. In the part of the town that was investigated and presented in this paper, the
consequences of the salt deposit exploitation on the ground surface are predisposed by complex terrain structure.

Keywords: ground deformation, salt deposit, complex structural-tectonic conditions
