The design scale of Guinean Boffa bauxite mine is 12 million tons/year. Under various harsh conditions such as rampant overseas epidemic and local election turmoil, the project team of the company strictly guards against death and organizes scientifically. The accumulated drilling footage is more than 30,000 meters, and the amount of bauxite ore transported abroad is about 52 million tons, which provides reliable resource reserves for the sustainable development of the mine. The project adopts spiral waterless drilling technology, which significantly improves the exploration efficiency on the premise of ensuring the drilling quality. At the same time, the three-dimensional geological model of the deposit is established by using three-dimensional software, which greatly facilitates the production management and stope ore matching of the construction unit, and shows the rich overseas construction experience and first-class laterite bauxite exploration technology level of the company.
