Open dataset contains data on underground mine workings and on reported impacts of mine workings over the territory of the Czech Republic. Attributes include detailed information about each object, e.g. the exact location, topographical situation, proprietary relation, technical data, the current state of these workings, their hazardousness and possible security measures. There are also links to the signatures of source reports stored in the CGS Geofond archive and to the digital documentation in *.jpg format - e.g. photograph, map cut-out, drawing.

Data from the database are continuously used in monitoring the safety of mine workings according to the Mining Act, in land-use planning, and as a part of the urban planning documentation according to the Building Act.

Open dataset contains localisation and the state-of-the-art of data on individual registered mining waste facilities in the Czech Republic.

According to Act no. 157/2009 Coll. § 17 Sec. 4, point. a) and b) CGS was commissioned by the Ministry of the Environment to identify closed and abandoned mining waste depositories that are significant risk to environment and human health. CGS maintains a register of these depositories.

Open dataset contains Information about the Protected territories for special intervention into the Earth’s crust in the territory of the Czech Republic. It includes (according to §34 of Act No. 44/1988 Coll., Mining Act) underground storages, underground depository of radioactive and other waste and industrial use of the Geothermal energy. These areas must be respected in the Urban Planning Documentation.

CGS provides data on undermined areas to public authorities and spatial planning authorities in accordance with the valid Building Act. Furthermore, this data is used in the assessment of mine workings impacts and the processing of complex information about the territory.
