Abstract: The results of laboratory experimental study of the production of the backfill autoclaved slag-concrete made of slag wastes and lime are considered in the article. The article proposes the method of filling the abandoned vertical mine shafts with the cylindrical large-size slag-concrete blocks, and the method of making blocks in the autoclave chamber on the surface of the mine. The developed backfill method allows us to ensure ecological safety of the territories adjacent to the vertical mine shaft and at the same time to utilize technogenic slag waste of the fuel and energy enterprises.

Key words: back filling of vertical mine shafts autoclave slag-concrete block autoclave curing
