Salt caverns are formed through solution mining of rock salt (halite or NaCl) as they are highly soluble in water. In this process, cylindrical or thick artificial pits in underground salt deposits are built (drilled) from the surface through the injection of water in a controlled manner into the rock salt [39, 63]. The salt surrounding the ...
