Surface mining, as a means of intensive exploitation of mineral raw materials and especially coal, is highly developed area of economy, therefore land degradation is intensive and leading to loss of the productive layer of soil. Biological reclamation of deposol should reduce the harmful consequences of exploitation. The number of systematic and physiological groups of microorganisms and their activities provide correlative infor­mation on the biological activity of the soil. In 2011, at the

The aim of the research is to the deposol biological activity in the process of biological reclamation based on the distribution of certain groups of microorganisms and dehydrogenase activity. General microbial activity in deposol in the process of reclamation is determined by the total number of bacteria, azotobacters, ammonifiers, oligonitrophyls, actinomycetes and fungi and the activity of the enzyme dehydrogenase.The research results indicated a greater abundance and deposol dehydrogenase activity in the process of biological reclamation compared to deposol (control).
