Summary
Large spoilheaps of overburden from open-cast coal mining in Northwestern Bohemia offer a space for development. However, they exhibit unfavourable features such as collapse potential caused by the lumpy structure with high overall void ratios. Suction oscillations contribute to the structure degradation by the intervoids closure. The paper presents in-situ suction monitoring and laboratory investigation of the collapse potential of spoilheaps.
