Abstract: The results of studies on the possibility of using coal and anthracite ash and slag mixtures at thermal power plants in Donbass for the manufacture of mine support elements operating in conditions of aggressive mine waters are presented. The performed studies showed that coal ash and slag mixture from thermal power plants can be used as a filler in the manufacture of reinforced concrete elements of mine support. Based on the research results, it can be recommended to use fine-grained dense concrete based on coal ash and slag mixtures at thermal power plants for repair work. Fine-grained ash and slag concrete based on coal mixtures at thermal power plants, in addition to good corrosion resistance to aggressive mine waters, have sufficient adhesion strength to heavy concrete based on natural aggregates and can be used for the repair and restoration of structures that have been in operation for a long time.
Keywords: mine support elements, coal ash and slag mixture of thermal power plant, anthracite ash and slag mixture of thermal power plant.
