Black River Tunnel project phase 1: Innovative quality control approach for installation and testing of rock bolts in shafts

Mining Engineering, 2015, Vol. 67, No. 6, pp. 113-115
Edberg, J.


PREVIEW:

This article details the use of an alternative testing method to the 2004 “Post-Tensioning Institute (PTI) Recommendations for Prestressed Rock and Soil Anchors” manual’s recommendations for temporary and permanent rock anchors for applications in shafts and tunnels. This method was developed and used for the Black River Tunnel (BRT) project in Lorain, OH as a means to reduce testing time of rock bolts during shaft construction while maintaining a similar level of quality control and assurance. The following sections will detail the project background, subsurface characteristics, shaft construction, the 2004 PTI testing method and associated difficulties, the alternative testing method and conclusions reached.
