Charcterization of Autoclaved Slag Concrete for Stowing the Vertical Mine Workings under Liquidation

Authors : Andrey V. Uglyanica, Kirill D. Solonin and Ekaterina A. Strukova

Abstract: Performance analysis of the vertical mine workings showed that hardening unshrinkable and waterproof backfill is the main guarantor of long-term sustainability of the earth's surface in the vicinity of the vertical mine workings under liquidation and ecological safety of territories. The study presents the results of the experimental laboratory studies of filtration and compression properties of the autoclave materials, based on the fuel and energy industry slag waste and lime for stowing the vertical mine workings under liquidation. The results of the study show the dependence of changes in the properties of autoclaved slag concrete on the stowing slag lime mixture parameters and its autoclaving. The obtained results allow determining the rational parameters of autoclave slag lime mixture for the production of shrink-proof and impervious stowing slag concrete in the vertical mine workings under liquidation. The regularities allow to develop the technology of backfill vertical mine workings under liquidation water-resistant low-shrinkage mining slag lime autoclave concrete and rational method for determining its parameters. Studies on the mechanisms of a process of forming the vertical mine workings under liquidation unshrinkable and waterproof filling mass autoclave method based on slag waste of fuel and energy companies are relevant to the solution of environmental problems areas liquidated mining enterprises and disposal of slag dumps. In addition, developed as a result of this study, non-shrink and waterproof slag-lime autoclave concrete will be used in the construction industry as an alternative to cement concrete.
