Waste Dump Development In A Tropical Environment

Innovative designs, mining, construction and reclamation practices are used at PT Newmont Nusa Tenggara's Batu Hijau mine on Sumbawa Indonesia to develop a cost-effective, environmentally sound, stockpile and dumping system. The mine production rate is over 200 million tonnes per year (50 million tonnes processed with 150 million tonnes being stockpiled for processing later or placed in waste dumps). Dump development for over 150 million tonnes per year in a mountainous, tropical environment, while meeting environmental and permitting requirements is not an easy task. The effective implementation requires innovative techniques and practices from every department of the mine.
