Abstract

O'CONNOR, D.M.  and  SERTIC, T.. Development of a remote-controlled rockbolting system for narrow-seam hard-rock mines. J. S. Afr. Inst. Min. Metall. [online]. 2020, vol.120, n.1, pp.91-96. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/851/2020.

This development of a semi-automated, remotely-controlled rockbolting system for use in hard-rock mines with a mining height of between 0.9 m and 1.2 m is described. The rockbolting system required development of fully mechanized, remote-controlled rockbolting rig, novel rockbolts, and a pumpable, fast-acting resin grout to secure the bolts. The rockbolter is one component of an equipment suite enabling full mechanization of rock-breaking by blasting, clearing of the broken rock and rock support. Development started in 2012 and the bolter has been operating on a platinum mine since 2017. Deployment of further equipment suites is planned for 2019.

Keywords : rockbolting; mechanization; automation; narrow reef; pumpable resin.
