Assessment of pillar stability is one of the most crucial steps in mine design (Sjöberg, 1992). South African platinum mines has reached a point where layouts made for shallow operations are insufficient due to increased depth, creating a necessity for new design
Overcoring is a measurement method used for estimating the state of stress in a rock mass. The method is based on measuring the strains that develop when a sample of rock, by drilling with a hollow core bit, is released from the
The Division of Waste Science and Technology at Luleå Technical University on behalf of and in co-operation with Telge Återvinning, Swedish recycling company, is developing a cover system with recycled waste materials, e.g. fly ash, digested sewage sludge and a mixture of
Besides the safety aspects, the economy is the single most important factor when bridges are designed. Lowering the life cycle cost of bridges means that less tax-money would be spent, and that should be in the interest of the general public. Today,
The purpose of this thesis is to study the influence of fire on the stability of tunnels. During the last few years a number of fires have taken place in tunnels. For example, the fires in the Channel and the Tauern tunnels
In order to carry out blasting operation with optimal results the influence of rock properties on fragmentation process and the quality of the aggregates should be studied with the proper thoroughness. Recent investigations of granitoid rocks infer that the resistance of rock
The aim of the project was to study the potential of borehole systems in Portugal, once its need for acclimatization is increasing. At the same time endogenous and renewable energies are important and necessary to be implemented in the country. The borehole
Composite bridges are used for road and railroad bridges in Sweden and worldwide. The advantage of composite bridges is that concrete and steel is used optimally, steel in tension and concrete in compression. In order to get the interaction between steel and
The mobility of antimony (Sb) in municipal solid waste incineration (MSWI) residues often exceeds the limit values stipulated by the European Union. As an ash treatment by washing is conceivable, this work investigated the Sb release from Swedish bottom ash and fly
Onsite wastewater treatment systems (OWTS) serve approximately 25 % of all homes in the United States. Conventional OWTS often require a lot of space to work properly and there are concerns over OWTS treatment efficiency for nutrients and pathogens. These concerns about
