Abstract
Mechanical parameters of rock salt are fundamental for designing and ensuring the long-term stability of energy storage facilities and waste repositories. Previous research has shown that rock salt samples from the same formation, deposit, or even bed exhibit vari- able mechanical parameters in standard laboratory tests. This variety is linked to petrological features (microfabrics) such as impurity content, the presence of fluid inclusions (FIs), and structural and textural patterns. Like other rocks, the mechanical behaviour of rock salt is controlled by mechanisms acting at the grain scale. However, the effects of microfabrics on mechanical properties and deformation behaviour of rock salt are not fully explored. To study this issue a device enabling uniaxial compression tests with simultaneous observations under the microscope was employed. Experimental mechanical tests in microscale were car- ried out on samples from Zechstein Polish rock salt deposits: pink rock salt from the Køo- dawa salt dome, grey and light grey rock salt from the Lublin-Gøogow Copper District (LGOM) as well as light-grey and two types (A and B) of white rock salt from Gora salt dome. The results of micro-mechanical tests showed that the mechanical behavior of rock salt is influenced by a complex interplay of microfabrics including FIs, amount and distribution of anhydrite crystals within halite grains and the shape of grain boundaries (GBs). These vari- ations of microfabrics are crucial for understanding a diversity in mechanical properties of rock salt as well as micro-cracks generation and propagation that contribute to the develop- ment of porosity and permeability. These findings are particularly significant for ensuring the safety of energy storage caverns, wastes repositories and mines.
