Abatement projects were undertaken to prevent or minimize further subsidence in Wyoming communities. The paper gives a brief historical background on the mining activity in Wyoming. Subsidence characteristics and occurrences in various communities are presented. The locations of the key abatement projects and the reasons for their selection is given. The selection criterion for the backfilling and grouting methods and the techniques themselves are presented. The problems encountered during various projects are discussed. Successful projects are analyzed. Based on the obtained experience, recommendations for future projects are given.
