In the large German coal mines, the overburden to coal ratio can reach 6 m³/t and the depth of the mines can be up to 300 m. The total amount of overburden removal is approximately 1 billion m³/a. To minimise the costs and the impact to the environment, the formation of inside dumps with high productive continuous mining technique is required. The formation of the dumps is influenced by several factors, like slope stability, stability of working benches, dumping of cultivation substrates on the surface, design of the landscape, surface water flows/erosion prevention and acid mine drainage (AMD) (Drebenstedt 2001, 2006). The paper introduces the specific conditions of overburden management and shows strategies for AMD control. It is presented as a mine planning and operational management system for optimal overburden dumping. %1 Perth %I Australian Centre for Geomechanics %U https://papers.acg.uwa.edu.au/p/802_12_Drebenstedt/ %R 10.36487/ACG_repo/802_12
