Abstract: This paper presents a case history of an abandoned mine mitigated by the dynamic compaction. The mitigation system consists of providing drainage path, filling voids, dynamic compaction and replacement procedures. The construction parameters of the dynamic compaction selection criteria are also discussed in the paper. The quality assurance testing results indicate that the mitigation is successful.
