Abstract: Rational use of waste mining and enrichment of coal attracts the attention of many researchers, since they are sources of raw materials for the production of aluminum, bismuth, gallium, germanium and other metals, as well as in road and hydraulic engineering construction. At the same time, for many decades, the coal mining of Donbas was accompanied by the accumulation of a huge number of rock heaps, including burning ones (burnt out). In this work, it is shown that the use of the burned-out rock mass as one of the raw material components in the production of building materials makes it possible to increase the strength of experimental samples of cement-rock mixtures by almost 2 times, and their frost resistance – by 1.5 times.
Keywords: coal mining, burning dumps, cement-rock samples, strength, frost resistance.
Pages: 96-99.
