    Common remediation method of inactive open pits is a partial or complete infilling with dump soil derived from removed overburden. A problems which rises during such remediation is a significant settlement of soils caused by its high compressibility. Recognition of compressibility and settlement enables the proper design of both required and final depths of the fill and allows to balance the required and existing volumes of dumped material. Authors proposed a calculation method for settlement of dumped fill deposited in an inactive open pit, which includes self-weight settlement and collapse settlement caused by recovery of groundwater table. The proposed calculation is based upon solution given by Nwabuokei & Lovell (1985) for settlement of fills composed of compacted soil. Examples of calculations are presented in which both the compressibility and collapse potential parameters were determined from authors' own studies.
