1. Extraction of Backfilled Tailings in the Dannemora Mine – Economic Potential and Rock Stability Assessment
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The cut-off grade determines what rock mass are economic to mine. At the Dannemora mine, in eastern Bergslagen, Sweden, previously processed ore generated tailings (enrichment sand) with an iron content of 21-22 % that was backfilled into large open bodies (stopes) in the mine between 2013-2015.

2. Decarbonising the Mining Industry: The Case of Dannemora Iron Ore Mine
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Swedish mining and minerals sector is one of the most prominent greenhouse gas emitters in the country. At the same time, it also provides Sweden and other nations with vast amounts of important metals and minerals, which are not easily replaced. LÄS MER
3. Induced Seismicity in the Dannemora Mine, Sweden
Master-uppsats, Uppsala universitet/GeofysikSammanfattning : Induced seismicity is a common phenomenon that occurs as soon as the stress state in the subsurface is externally altered in a way that faults are destabilized. It is especially problematic in stable tectonic regions where the area is not used to earthquakes; the infrastructure is not built to withstand ground movement and thus when the induced seismicity occurs damage can follow.

4. Mineralogical Study of Manganese Bearing Skarn Minerals and Manganese Content in Magnetite in the Dannemora Skarn Iron Ore Deposit
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Dannemora skarn iron ore deposit is located in the northeastern part of Bergslagen. The deposit has been mined from the 1400’s and stopped in 1992, the mine was reopen in 2012 and it will close in 2015. The Dannemora deposit is hosted by 1.9 Ga old sedimentary and volcanic rocks.

5. Modellering av flöden och syrgasförhållanden i Dannemorasjön och dess tillrinningsområde
Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Det hydrologiska systemet i Dannemorasjöns avrinningsområde, beläget i norra Uppland, är mycket komplicerat och har förändrats genom åren på grund av mänskliga ingrepp. De naturliga sjöarna i området har vid flera tillfällen utsatts för stora sänkningsföretag, vars främsta syfte var att förhindra läckage till gruvan i Dannemora.
