Abstract:

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.

Keywords: Salt, underground excavation, stress, numerical analyze
