The final slope of Une mine experienced sudden increases in displacement in specific sections during the typhoons of 2007 and 2011, as observed through long-term monitoring since the excavation from the top. The rise in groundwater due to increased r

The Une Mine excavates limestone by the bench cut method at Mt. Buko in the Chichibu area of Saitama Prefecture, Japan. Since the final rock slope, which is the largest scale in Japan, is beeing constructed at Mt. Buko, long-term monitoring and analy

In the present study, the relation between groundwater fluctuations on a rock slope and the dis-placement of the Mt. Buko rock slope is analyzed. In general, the strength of a rock mass behavior is subject to the influence of water. Rock slope stabil

Mt. Buko's rock slope has been formed by mining activity since 1973 and it will be 800 m high and 5 km long at the end of the mining operations. To manage the rock slope in a stable condition over the long term, mining companies operating at Mt. Buko

Surface mine planning techniques are reasonably sequential and consist of geological modeling, deposit ranking, pit design and scheduling. In all deposits a pre-requisite is a sound geological model. Ranking uses such a model to find the economic pit
