- Obvodní báňský úřad v Mostě
The paper brings an overview of the history of the mine of Kohinoor since the opening until the abandonment, except for the abandonment of the last two vertical workings - shafts K 1 and MR 1, which were not abandoned due to a change in the mine abandonment project. The order of mine workings abandonment as well as the way of the abandonment of the opening vertical mine workings is described. Overall, the abandonment of nine mine workings is characterized here, since 1967 until 2003. Moreover, the time sequence of using different backfilling methods is also mentioned, i.e. partial backfilling using loose material, using loose material in the full height of the pit shaft, or using consolidated material in the full height of the pit shaft.
