Simandou Iron Ore Project
Located in the Simandou Mountains of southeast Guinea, Simandou iron ore mine is expected to produce 100 million tonnes of iron ore per year. The project included a 650km long railway to transport the extracted iron ore to the west coast. A Ground Improvement Advisory Group (GIAG) was formed to research ground improvement technologies for an iron ore stockpile and handling facility on the Tannah Peninsula.
The site presents geotechnically challenging conditions including the possibility of ground treatment being required – up to 20+m thick. The particular engineering issues to be considered were the settlement, stability and possibility of liquefaction (due to earthquakes and how the appropriate ground treatment technology may be used).The Simandou project differs from Port and Reclamation projects because the 1km x 2km area for stockpiling (included loads exceeding 200kPa, due to the weight of the iron ore).
