Paper presented at the ISRM International Symposium – EUROCK 2021, September 21–24, 2021
Paper Number: ISRM-EUROCK-2021-158
... Abstract Over the last decade, large rock caverns have been developed for storing vast volumes of hydrocarbons and in particular crude oil. In this context, large rock caverns have light support made of grouted steel or fibreglass rock bolts. Reinforcing cables are strictly prohibited to avoid...

Paper presented at the ISRM International Symposium – EUROCK 2021, September 21–24, 2021
Paper Number: ISRM-EUROCK-2021-091
... Abstract A new underground powerhouse that combines a run-of river scheme with a pumped storage scheme is planned in course of the Renewal of Forbach HPP in Germany. The powerhouse cavern is designed to have a maximum span and height of 18.9 and 42 m, and a total length of 123 m. The rock mass...

Paper presented at the ISRM International Symposium - EUROCK 2020, June 14–19, 2020
Paper Number: ISRM-EUROCK-2020-058
... Abstract The global demand onto large volumes of hydrocarbons to be stored in rock caverns lead to the development of very large caverns. The larger the cavern sections, the larger the potentially unstable blocks and the risk of megawedges. The hydrodynamic containment of hydrocarbons...

Paper Number: ISRM-EUROCK-2016-147
... ABSTRACT: Since several years, the demand for the storage of gas in rock salt caverns has changed from seasonal to high cycling operation. The new operation mode requires relatively fast pressure change rates in the cavern which in turn leads to temperature changes in the gas. The consequences...
