초록
In many countries, there has been an increase in the number of renewable energy systems installed and operated inabandoned mine sites to promote the reuse of abandoned mine lands. Nowadays, 90% of mines are either closed or abandoned inKorea; most are left unattended. This study assessed the photovoltaic (PV) potential at abandoned mine reclamation sites in Koreausing renewable energy resource maps. Using geographic information systems, a spatial database was constructed for 218 abandonedmine reclamation sites that can be classified into five types: water treatment, forest recovery, soil restoration, tailings treatment, andsubsidence prevention. The top 10 sites with high annual total global horizontal irradiance (GHI) were selected by performing overlayanalysis to combine the solar energy resource and mine reclamation maps. The statistics of the annual total GHI at each type ofabandoned mine reclamation site and those at each administrative district were provided. In addition, the system advisor model byNREL was used to conduct energy simulations based on the weather data and 100 kW PV system design at the Samsan Jeil mine watertreatment site with the highest annual total GHI. The results indicated that the proposed PV system could generate 111,490 kWh/year.
