About
This document describes a NIOSH study on developing a practical method of measuring shotcrete adhesion strength in underground mines. A more thorough understanding of the in-situ strength properties of shotcrete, particularly the bond strength of shotcrete to the rock, will lead to improvements in ground support practices, thereby preventing ground falls and reducing mine roof-fall incidents
