Effect on surface deformation resulting from mining activity on value of property valuation. A case study from Jastrzębie- Zdrój region

Abstract The subject of the research presented in this article is the effect of subsidence resulting from underground mining exploitation on the value of non-developed real estate intended for residential construction (excluding multifamily) in Jastrzębie-Zdrój region. The article describes methodology, which helped in creating a map of average unit prices of non-developed residential properties and a map of subsidence in years 2008-2017, as well as a chart comparing these two issues. The results of the research show a relation between subsidence and nondeveloped residential properties value.
