A case study of a landslide, which threatened vital infrastructure
essential for the continuous operation of the Ok Tedi copper mine
is presented. The paper presents a detailed description of the land- slide, outlines the assets at risk, and how the issue was addressed.
This included the consideration of remedial options and the im- plementation of the most economically sound and geotechnically
feasible remedial design which was completed within budget and
on schedule. The paper is intended to highlight the responsibility of a mine
based Geotechnical Engineering section in providing essential
geotechnical investigations, design and professional advice on
addressing stability issues in the infrastructure region.
