Оценка и снижение экологической опасности отвалов горного производства в Новороссийской промышленной агломерации
Abstract
dc:description.abstractAbandoned non-reclaimed marl mine dumps of the cement factory in the Novorossiysk industrial agglomeration (NW Caucasus, Russia) are hazardous because of fugitive dust emissions, erosion and possible occurrence of a debris-flow disaster. Having high sorption capacity, dust accumulates pollutants contained in the atmospheric air and subsequently precipitates on the topsoil. Soil and plant sampling and chemical analysis (> 200 specimens) revealed the geochemical anomalies of Pb, Zn, Cu, Ba and Sr. Land zoning based on accumulated environmental damage indicators and the debris-flow technical risk was performed to assess environmental threats. The designed mine dump reclamation includes soil stabilisation by application of geosynthetic cover, hydro-seeding of soil improvers and seeds of herbaceous plants on the slopes, and anti-erosion plantation of cades and smoke trees at subhorizontal surfaces.
