Engineering geological conditions for the construction of a photovoltaic power plant on coal tailings

Abstract

Photovoltaic power plants have recently become increasingly common to reduce carbon emissions into the atmosphere. Non-fertile lands occupied by industrial waste are very suitable for their construction. The present study concerns the design and construction of a photovoltaic park on the territory of a reclaimed coal tailings dump “Suhoto Dere” near the TPP “Bobov Dol”. The study includes collection, processing and analysis of archival materials, site mapping, drilling of exploration boreholes, dynamic penetration tests, geophysical electrical resistivity survey, laboratory testing of soil samples to determine physical and mechanical properties; chemical analysis of soil samples to assess soil aggressiveness to concrete and steel. Based on the obtained data, an assessment of the suitability of the site is made and recommendations are given to prevent the occurrence of adverse phenomena and processes.
