| Summary: | Field and laboratory tests and analyses This Licentiate thesis deals with the function of shotcrete as rock support. An extensive failure mapping of shotcrete in the Kiirunavaara mine has been conducted to improve the understanding of the performance of shotcrete. Furthermore, the adhesion strength obtained for different types of scaling/cleaning methods and the relationship between adhesion and compressive strength were investigated in field tests in the mine. The failure mapping showed that most of the observed failures of shotcrete are in areas with a thin shotcrete layer ( === <p>Godkänd; 2001; 20070313 (ysko)</p> |
