Opencast mining in the Kuzbass is carried out using gidromehanizatsionnyh technologies that are the most progressive and effective ways to excavate in arrays composed of Neogene-Quaternary deposits. In addition, hydromechanization a single indissoluble chain processes that integrate development, transportation and stacking of disturbed rocks in special facilities – gidrootvaly. Basic technological processes hydromechanization include: the destruction of rock massifs hydro, dredges and non-pressure streams of water pressure or free-flow hydraulic transport; gidrootvaloobrazovanie.
Consider the case of partial removal of hydraulic mine dump in the Kuzbass region in connection with the need to retrieve from under him mothballed coal reserves. The results of geotechnical studies alluvial array: the physical and mechanical properties of alluvial rock and measurement of pore pressure in them. The problems of research and some methodological techniques. We settle the question of creating a new sustainable construction is part of the hydraulic mine dump.
