1. Design fires in underground hard rock mines
Abstract : During several decades considerable research activities have been conducted with respect to fires in coal mines, but the research activities with respect to hard rock mines have been limited. As the hard rock mines are getting more complex the need for deeper understanding of fires in underground hard rock mines are getting more in demand. READ MORE

2. Mine-scale rock mass behaviour at the Kiirunavaara Mine
Abstract : The interaction of the geological and mining environments leads to a variety of forms of rock mass behaviour, including seismicity and falls of ground. A precise understanding, however, of the role of geology in rock mass behaviour experienced by Luossavaara-Kiirunavaara Aktiebolag’s (LKAB) Kiirunavaara Mine remains unknown. READ MORE

3. Strength, fallouts and numerical modelling of hard rock masses
Abstract : The prediction of compressive stress-induced failures is of concern for the design and construction of deep underground excavations in mining and civil engineering. An overstressed rock mass may result in fallouts of rock, which may cause occupational safety hazards, damage of equipment, and/or production disturbances. READ MORE

4. Deformation and failure of hard rock under laboratory and field conditions
Abstract : The understanding of the fracture mechanisms and failure processes of the rock is an important requirement for the design of mining excavations and civil engineering constructions. The fracture process is necessary for the excavation and fragmentation of rock, but fracture of rock must be avoided and controlled to preserve the integrity of the construction. READ MORE

5. Alkaline by-products as amendments for remediation of historic mine sites
Abstract : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. READ MORE
