Abstract

Construction of storage caverns in salt deposits—geological and mining aspects.A b s t r a c t. In the last two decades two underground storage facilities were constructed by leaching caverns in salt domes in Poland. Although the storage facilities appeared successful, many wrong ideas about geological and technical problems connected with the underground storage in salt caverns are still popular. Therefore, the paper presents a brief review of the most important aspects of this subject along with history of underground storage in salt caverns, types of storage facilities and geological and technical conditions to be met in selection of the site. Moreover, the problems of water supply and brine recycling or disposal are also discussed and issues connected with spacing, shape and size of caverns and tightness and operation pressure ranged are presented.
