Abstract:
This paper introduces the Falcon Bolt – a self-drilling hollow bolt with a unique mechanical anchoring system developed for use in the underground hard rock mining environment. The Falcon Bolt aims to deliver several key innovations including reduced installation time, pre-tension during installation and high dynamic capacity. This paper will present the results of comprehensive testing and demonstrate how a datadriven iterative process was implemented to refine the Falcon Bolt’s performance characteristics. Testing methods include static pull testing, independent dynamic testing at Canmet and in situ installation verification.

Keywords: self-drilling bolt, rockbolt installation efficiency, rockbolt design, dynamic ground support
