Our Thiess team in Indonesia, working with our specialists in Australia, has designed a progressive program of annual campaigns for optimised waste dump rehabilitation. Aligned with life-of-mine services, it involves planning and design, material testing and encapsulation, and bulk earthworks. Outstanding results have been achieved while addressing acid mine drainage challenges, using rigorous material management and quality assurance. Innovative rehabilitation design and water management solutions, including using tyres for drainage, ensure the long-term safety and stability of rehabilitated areas in this high rainfall environment. Re-contouring is carefully staged for slope stability and topsoil preparation is designed to increase infiltration and control erosion.
