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

    Author : Göran Tuomas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    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

  4. 2. System for water driven down-hole hammer drilling

    Author : Göran Tuomas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Drilling with water driven down-hole hammers is a recently developed method for competitive production of boreholes. The technology requires large flow rates of preferably high quality fluid to drive the hammer tool. One method to reduce the consumption is to process and recycle the used drilling fluid. READ MORE
