Soil environmental issues of coal-mining in Baganuur and Nalaikh, Mongolia
(2023) Martin Knippertz; Enkhjargal Sodnomdarjaa
This study focuses on the environmental issues of mining (related) activities in Mongolia, with a focus on soils in the coal mining areas of Baganuur and Nalaikh. Besides the ecological components (including erosion), also the socio-economic conditions are of importance for the derivation of recommendations for a better understanding and management of Mongolia’s environment. The soil features in both research sites are generally good, heavy metal concentrations are within the guidelines, accept for Arsenic (As) showing increased values. The Geoaccumulation index and the Surface enrichment factor indicate no major influence of mining activities on the soil quality around the mining. However, soil erosion increases near mining sites, which can have a negative impact on soil quality. Studying the long-term effects of mining on the soil and environment in Mongolia is one of the country's most important concerns. In this context, the aspect of rehabilitation in mining areas is becoming more and more important in Mongolian society. Ecological and especially geotechnical recommendations for the management of Baganuur’s and Nalaikh’s environment are of importance for the stakeholders.
