Abstract (in english)
   The project is sub-divided into three independent tasks. DU-01: All data regarding negative impact of raw-material mining of geological environment have been compiled in the Protected Areas of Český kras, Litovelské Pomoraví, České Středohoří and Třeboňsko. The impact of mining has been evaluated from the point of view of geology, engineering-geology and hydrogeology. The protection of landscape components, important paleontological localities and a system of ecological stability has been discussed with the relation to a reduction of potential mineral resources and a mitigation of negative mining activities carried out inside these areas. The maps showing all aspects of ecological protection are enclosed. DU-02: The development of a register of areas affected by mining, areas remedial and revitalized has been established. Computer modelling involve analytical and stattistical model comprising system, structure and soft-ware for the collection of data.
   It will help to monitor the fluctuation of respective areas during a time, and the need for site assessment necessary for the district planing of ecological stability. It is accompanied with comprehensive documentation and an example map of recent situation in the selected district of Pardubice. DU-03: The geophysical, petrophysical, hydrogeological and geochemical data have been collected and sorted from an oil and gas deposits of Hrušky, Ždánice, Rusava and Krásná-Dolní Lomná. The evaluation of results revealed the relation between processes of fluid migration above oil deposits and processes of radioactive elements re-distribution. The main initiator of the fluid movement is a light fraction (methane to propane) bleeding from oils into the water system thus forming a steady pressure of the migrating front. Other important factors are pH and Eh, temperature of the environment, state of migrating ions and a composition of the solution.
   These processes of radioactivite element changes may as well exist in the sediments contaminated by oil and oil products of the anthropogenous origin
