ROMONTA CASE STUDY Achieving over 95% accuracy in a complex historical mining district with the ABB MineScape mine planning model2 CASE STUDY ROMONTA — The customer ROMONTA is the world’s largest crude montan wax producer. It operates the Amsdorf opencast mine, located in the Central German lignite mining area. From the bitumen-rich soft lignite, approximately 15,000 tons of crude montan wax are extracted per year from 500,000 tons of lignite. Over the past 100 years, the deposit has been mined underground and opencast (in the outskirts of the mining area). The high-grade mineral allows today’s economic extraction with opencast mining. — The challenges When designing a mine site, an accurate geological model is an important foundation for the extraction planning.
