Ash dump design

Ash dumps are essential to ensure the operation of coal-fired thermal power plants and boiler plants. Their role is especially high in conditions of combusting the high-ash coals of national coal deposits by heat and power facilities, as well as in conditions of extremely low share in the use of ash and slag waste by construction, road-building, and other enterprises of the country.

Hydraulic Engineering Department of the Institute develops projects of construction of ash dumps for hydraulic, dry, and combined stocking of ash and slag waste. At that, a special attentions is paid to issues of ash dump structures' seismic resistance and environment protection during the ash dump construction and operation.

Projects of construction, expansion, and modernization of ash dumps developed over the last years

  • Second stage of ash dump at CHPP-3 of "Pavlodarenergo" JSC;
  • Modernization and expansion of ash dump at CHPP-3 of "AlES" JSC using the combined system of ash and slag stocking;
  • combined system of ash and slag stocking at CHPP-1 of "AlES" JSC;
  • Ash dump No.2 at CHPP-2 in Astana;
  • Tailing dump of the Aksu Ferroalloys Plant.
