Nowadays hundreds million tons of ash and slag waste (ASW) is produced in Russia yearly. Large territories are needed in order to store such a big waste volume. Besides, it is necessary to conduct special engineering and ecological work at the design and usage stages of this structure. The goal of the research is to outline acceptable ASW utilization methods accumulated in coal burning power station ash dumps and to determine the order of activities to solve the problem. The research methods: experimental where Kansk-Achinsk and Kuznetsk coals are the object of the research. Besides, review of relevant to the problem literature and normative documentation was done to determine activities order, possible ways and limitations of the problem solving. We elucidated that ASW transportation to depleted coal quarries to restore them is essential to arrange in order to solve the problem of ASW utilization. As to new produced ASW, they should be divided into groups according to application field (mostly in construction). The groups correspond to boiler unit load operation. After coal combustion ash is stored in special places (reservoirs, silos). Therefore modern boiler unit might be seen as a production complex of steam and ash and slag material of an adequate quality.
