Characterizing the excavation process associated with removal of shotcrete reinforced underground structural liners using waterjet technology
The primary objective of this research is to characterize the operating parameters and fragmentation mechanisms associated with the hydroexcavation of reinforced shotcrete and concrete liners used in underground mines and tunnels. Through empiric testing, this research also seeks to validate the hypothesis that waterjet removal of these support systems will result in greater selectivity and less unintended damage than conventional removal methods. The intent is to develop a viable technology that will reduce the collateral damage caused to surrounding liners during excavation, improve the adhesion ...
