Abstract:
Installation quality of ground support elements is critical to the overall safety of underground mining environments. Visual inspection of rockbolt installation quality is a common practice. For some products it is difficult to visually determine a successful installation. The Sandvik MD and MDX bolts are examples of bolts which are difficult to visually determine correct installation, due to the blind nut configuration lacking tail protrusion. Sandvik has recently developed the peg bolt, a simple reliable visual indicator of bolt rotation to provide mine site personnel with an easy method to visually inspect bolt installation quality. This device has the capability to improve and simplify ground support installation quality assurance practices of the mine site. This paper will present the development of the peg bolt along with a case study.
