- The aim of the work is to study the use of slag aggregate concrete for the construction of monolithic concrete lining of mine workings. In the coal industry the average of 10-15 m of development workings are constructed to extract 1,000 tons of coal. The monolithic concrete is 97-98% of the total material consumption for the construction of vertical shafts in Kuzbass; lining costs being 50% of the total cost of shaft construction, which are directly dependent on the material consumption and cost. Considering the amount of annually produced coal in Kuzbass mines, it becomes obvious that the cement consumption in the industry amounts to several million tons, the consumption of the aggregates is about ten million cubic meters. It was found that 25-30% of concrete-lined mine workings are re-lined annually. This is due to the concrete destruction under the influence of unfavorable operating conditions, especially the destructive action of mine water. Therefore, the problem of production of concrete capable of withstanding these phenomena seems quite relevant.
