Technological researches of coal mining waste with its processing and utilization to build-up production of constructional concrete in the north

Annotation

The article reviews a current state of waste use in the coal-mining industry to produce porous fillers of light concrete, ceramic materials and products taking into account the modern market relations in the conditions of Far North territory development and the Arctic sea shelf as well. It solves an important environmental problem such as the reduction of harmful emissions of greenhouse gases from the smoking waste heaps of the coal mines which work with thermal power plant relating to monotowns of the Pechora coal basin, Vorkuta and Inta. The construction industry, considering the exhaustion of the mineral deposits, is able to recycle the sub-standard clay soils which litter the surrounding nature and it is useful to use them with technology cost reduction. Agloporite is a material in the form of crushed stone, gravel and sand. It is received by means of agglomeration, but not by blowing-up of clay breeds and waste after production, processing and burning of fossil coals. On porous filler, agloporite, we receive constructional light concrete of 300-500 brands to produce covering and overlapping plates, building walls including monolithic housing construction, wall concrete blocks at the reconstructed operating production industries with batching plants. Their application will give the chance to increase heat-shielding qualities of buildings and to cut down transportation costs.
