Contemporary Biological Methods of Mine Reclamation in the Kemerovo Region – Kuzbass

Abstract

Introduction. Coal mining is the main source of anthropogenic impact on the landscapes of the Kemerovo Region – Kuzbass. The current mine reclamation rate lags far behind the annual increase in disturbed lands. A reclamation fund can be a perfect solution to this relevant issue. The present research objective was to analyze and structure the available data on the anthropogenic impact of coal mining in Kuzbass. The article reviews new effic ient methods of reclamation and resoiling. Study objects and methods. The study featured ten years of research publications that were registered in the PubMed database of the National Center for Biotechnology Information (USA), Elsevier (Scopus, ScienceDirect), the Web of Science, and the Russian Electronic Library (eLibrary.ru). Results and discussion. The research revealed the following Kuzbass districts that experience the greatest mining impact: Novokuznetsk, Prokopyevsk, Kemerovo, Belovo, and Leninsk-Kuznetskiy. The authors also identified the most common pollutants associated with coal mining. Polycyclic aromatic hydrocarbons (PAHs) appeared to be the most dangerous pollutants: as waste coal burns, these substances cover considerable distances with the wind. Biodegradation seems to be the optimal solution because PAHs are known to be carcinogenic, and most mine tips are located near settlements. The article also features mine reclamation laws and introduces a list of plants with a high absorption capacity recommended for biological reclamation, as well as microorganisms and their consortia used for bioremediation. Conclusion. The authors identified the most promising methods of mine reclamation in the Kemerovo region, i.e. bioremediation with pollutant-binding microbial consortia and plants.
