The reasons for using SFRS, including the way a SFRS performs in comparison to plain shotcrete as a support element in mining tunnels, are discussed. The mechanisms by which steel fibres reinforce shotcrete and the need for specifying performance criteria are highlighted. A description of current testing procedures, including an overview of quantitative' design recommendations provided from various international authorities, is provided. A summary of international recommendations on suitable qualitative' performance classifications is also reviewed, including a critique of their suitability. Finally recommendations on the practical considerations necessary to ensure good quality, in-place SFRS, are made, including a calculation method for determining minimum steel fibre dosages.
