Paper Number: ISRM-Rockstore-1980-056
... Harvested grain is effectively stored in rooms left 15 to 65 meters underground mined out in the production of limestone for aggregate. The rock production subsidizes the cost of excavation and the use of these rooms for storage becomes a dual economic gain. Dry, cold, and frozen sections for...

... plant, a 300 m deep test hole was drilled at Ontario Hydro's Darlington site approximately 65 km east of Toronto. The hydrofracturing method was used to determine the state of stress in the Paleozoic limestones (0-220 m depth) and the Precambrian granitic gneiss (220-300 m). The results of these...
