About Ways of Utilizing Coal Mining Overburden Rocks in Construction Technologies

The paper considers the development of coal mining closed-cycle technology in Kuzbass based on the example of the Zarechnaya mine operation in Polysaevo, Kemerovo region. Purpose: Substantiation of some ways of utilising overburden rocks in construction technologies. Special attention is paid to theoretical and experimental substantiation of overburden waste utilization in construction. Methodology: The emission spectral analysis using a spectrometer Grand with a multichannel analyzer of emission spectra; a derivatograph is used in these studies. Research findings: It is shown that the overburden rocks are a combination of minerals from the main rocks of calcium, aluminum, magnesium, silicon and other elements. Based on physicochemical studies of the composition and structure of overburden rocks, methods are proposed for their processing into construction and composite materials for various technical purposes, made on the basis of mineral and organic binders.
