Senior advisor in Pyhäsalmi “New Mine Project” and “Kemi Underground Mine” projects in Finland. Outokumpu coordinator in the “Intelligent Mine technology project”. Outokumpu representative in Silver Swan Ni-mine (Aus) Feasibility study team and Zaldivar Cu mine (Chile) FS team. Author of several conference texts dealing with rock mechanics applications (like cable bolting, dilution control) in underground mining.

Dr. Bjørn Nilsen received his Master- and PhD-degrees from the Norwegian Institute of Technology (NTH). Since 1985 he has been Professor of engineering geology at NTNU, the Norwegian University of Science and Technology, interrupted by 2 years as visiting professor at Colorado School of Mines in the US. Before joining the University he had 10 years of experience from consulting and mining industry.

Professor Nilsen has extensive experience on various aspects of rock engineering, including site investigation, planning and design, stability analyses and construction control. He has been acting as Expert advisor of several large projects in Norway and abroad and is covering a wide area with main current projects on subsea tunnelling, engineering geological aspects of mechanical excavation, hydropower tunnelling and rock slope stability analysis.

Professor Nilsen a Former President of the Norwegian Tunnelling Society (NFF), and is also Chairman of the Scientific Committee for the upcoming ITA World Tunnel Congress in Bergen, Norway in 2017.

Beatrice Lindström has a MSc i Civil Engineering and a Technical Licentiate Degree in Rock mechanics from Luleå University of Technology, Sweden. She has worked 10 years at WSP as a rock engineer and one year at Golder Associates as the team manager for the rock engineering group. Since 2011 she is working at Swedish Transport Administration (Trafikverket) as the Design Coordinator for the rock tunnel contracts in the E4 Stockholm bypass Project, a major project in Stockholm. The work covers management of the design of the tunnels for a total building cost of about 1 billion euros. Beatrice has around 15 years of experience of rock engineering design and about 3 years of research in stress measurements.

Jimmy Töyrä has a MSc in Civil Engineering and a Technical Licentiate Degree in Rock mechanics from Luleå University of Technology, Sweden. He has worked two years at Vattenfall Power Consultant AB as a rock engineer and three years at Swedish Transport Administration (Trafikverket) with management of railroad tunnels. Since 2012 he is working at LKAB as the manager of rock mechanics at research and development.

Per-Ivar Marklund has a MSc in Mining Engineering and Rock Mechanics from Luleå University of Technology, Sweden. During the 27 years of rock mechanics work within Boliden, of which the last 19 as manager for , Per-Ivar Marklund has gained experience, skills and knowledge through internal and external research projects and as a member of different organizations for research and development within the field of rock mechanics but mostly through the work in internal projects for new mines, rock mechanics of mining methods in open pits and underground, rock support and geohydrology, i.e. all aspects of rock mechanics in mining.

Stefan Geir has a BSc in Geology from the University of Iceland and a MSc in Engineering Geology and Rock Mechanics from NTNU, the Norwegian University of Science and Technology. Since graduation from NTNU in 2008 he has worked for EFLA consulting engineers in Iceland as an engineering geologist. He has been involved in planning, design and construction supervision in tunneling projects, hydropower and road tunnels, in Iceland, Norway and Chile.
