Abstract:
Russia is one of the world leaders in coal production. In-place coal reserves of Russia account for one third of total world coal reserves and one fifth of world explored reserves. At that, some 4-5 t of overburden rock is stripped in surface mining and up to 0.2-0.3 t of mine rocks are produced in underground mining per of 1 t of mined coal. In addition, in the process of coal preparation in 2016 more than 30 mln t of solid waste were generated and on coal-fired thermal power plants 25 mln t of ash and slag waste (ASW) were produced.
Solid wastes of coal mining, preparation and burning are discharged to dumps which occupy large areas of valuable ploughlands, worsen landscape of the territory, are the sources of environmental pollution, and their storage involves relatively high capital and operational costs.
A sustainable solution of the problem of efficient use of industrial waste depends on several factors, namely, material composition of waste, its aggregative state, quantity, technological characteristics, etc.
The problem of non-waste technologies has ecological, resource saving, technological and technical, economical and organizational aspects.
The areas of efficient use, technical requirements, technical solutions and innovative trends in the processing of technogenic coal deposits have been determined based on the analysis of basic regularities of development of their physical and chemical properties, aggregative state, quantity and natural heterogeneity.
