Mine Closure

Integrated mine closure planning, design, & implementation

BGC provides integrated services to develop closure plans and closure landform designs for proposed and existing mines. We incorporate the mine plan, as well as the geotechnical, geochemical, and hydrotechnical aspects of the site, to effectively design and schedule the practical reclamation of mine components to meet closure goals and achieve the post-mining land use. Our multi-disciplinary team partners with re-vegetation experts to deliver comprehensive mine closure services.
