Abstract

LABUSCHAGNE, J.P.; YILMAZ, H.  and  MPOLOKENG, L.. Critical investigation into the problems surrounding pillar holing operations. J. S. Afr. Inst. Min. Metall. [online]. 2015, vol.115, n.4, pp.307-312. ISSN 2411-9717.

An investigation into pillar cutting was carried out at a platinum mine on the western limb of the Bushveld Complex. The focus was on crush pillar design and implementation in order to ultimately improve the compliance percentage for pillar cutting. The major findings from the investigation suggest that the pillar cutting problem lies with the implementation of the design rather than the design itself. Observations of the practical issues underground that prevent good pillar cutting were made. After these issues had been identified, recommendations to rectify these problems and a few other issues identified during the investigation were provided. The recommendations are aimed at improving the pillar cutting compliance and reducing the likelihood of pillar bursts or pillar runs, which will ultimately create a safer mining environment.

Keywords : crush pillar; design; practical issues; implementation.
