ABSTRACT

In Poland the closed shafts were filled up in the past years with the rock material with
very different backgrounds and properties. The effect of flooding the shallow, old mining areas, as well as the impact of water infiltrating from the surface, are observed on the surface as subsidence funnel and discontinuous crack. Using the geophysical
surveys, numerical modeling, geological and hydrogeological studied, some possibilities for diagnosis of hazards in abandoned coal mines areas are shown. In the context of risk assessment pointed out the necessity to conduct such research in the long
time following mine closure. It is necessary for the spatial development plans and for safety use of post mining areas. Brief description of the study and the methods used.
