The use of underground excavation in salt-rock formations for waste storage imposes the precise analysis of properties of salt rock and a stress analysis. One of the main mechanisms responsible for a degradation of isolation ability of the rock salt is the generation and development of cracks under influence of mining processes. Various aspects of cracking in salt rocks are studied both in situ and in laboratory tests for rocks of the Targu Ocna Salt Mine. The aim of this paper is to describe the time behavior of rock-salt around underground mining excavations and in situ stress monitoring system of rock mass was proposed.
