    Abstract : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. READ MORE

    Abstract : In the beginning of 2005, the ministry of natural resources in the Kurdistan region of Iraq dividedits territory into more than 50 oil blocks based on geological setting. These oil blocks were awardedlater to different international oil companies for oil investments based on Production SharingContracts (PSCs). READ MORE

  4. 4. On the Nature of Cemented Carbide Wear in Rock Drilling

    Author : Ulrik Beste; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; cemented carbide; wear; rock drilling; rock; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : WC/Co cemented carbide is a composite material for highly demanding wear applications. The unique combination of hardness (from the WC-phase) and toughness (from the binder Co) gives a material especially suitable for rock drilling. READ MORE

  5. 5. Water powered percussive rock drilling : process analysis, modelling and numerical simulation

    Author : Göran Tuomas; Luleå tekniska universitet; []

    Abstract : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. READ MORE
