Engineering-geological and ecological concerns in operation and reclamation of high slope dumps at open-pit mines in Kuzbass

A brief review of the domestic researches into the engineering-geological and ecological safety of operation and reclamation of different-type external dumps at open-pit coal mines in the Kuznets Coal Basin (Kuzbass) is implemented. The lithological and engineeringgeological characteristics of overburden rocks at open-pit mines and at dumps and hydraulic fills in Kuzbass are described; the regional features of engineering-geological conditions of dumping are discussed, namely, strength characteristics of manmade dumps and hydraulic fills, as well as natural rocks under vertical loads equivalent to loading applied by high and super high dumped structures. The influence of various-type overburden dumps on geoecology in the adjacent areas of surface mining is assessed, and the hazard classes of overburden rocks in the dumps are determined. Suitability of macroand microelement composition of overburden rocks in dumps and hydraulic fills for the future biological reclamation is determined, and the influence of grain-size composition and microaggregative state of the dumps and fills on the formation of fertile soil layer in biological reclamation is estimated. The efficiency of overburden waste rocks in recovery of manmade-disturbed lands in Kuzbass is proved.

Keywords: dump, hydraulic fill, manmade rocks, engineering-geological conditions, strength properties, geoecology, manmade landscape, reclamation.
