The Czech Republic has long been among the significantly industrialized countries in the Central European region. New social, but also economic changes and plans often affected many archaeological sites and large parts of the landscape. Extensive brown coal mining has continued here for many decades, changes in infrastructure and communication networks have initiated a boom in the mining of various building materials from stone to limestone to gravel and sand materials. The establishment and expansion of mines and quarries often irreversibly changed the landscape and the condition of many archaeological sites. Examples of timely applications of non-destructive geophysical measurements in the vicinity of quarries can also demonstrate effective procedures both for the implementation of rescue archaeological research and for changes in the demarcation of undisturbed parts of important immovable archaeological monuments.
A magnetometer survey at the Vražkov, Litoměřice district confirmed the continuation of a prehistoric polycultural burial ground in the eastern vicinity of the previously excavated sand quarry and initiated a new project archaeological investigation of the preserved part of the long Eneolithic burial mound. An extensive geophysical survey of the polycultural prehistoric and early medieval hillfort of Plzeň-Hradiště, district of Plzeň-město contributed to the definition of the extent of the old and already buried sand quarry inside the protected area of the site as part of the systematic archaeological investigation of the site's fortifications. A systematic survey of the inner part of the prehistoric and medieval hillfort in the Hostim, Beroun district provides a basis for the site protection of the previously partially disturbed by limestone quarries. Extensive surveys with a magnetometer at the Libkovice/Marianske Radčice, Most district in the forefield of the brown coal mine greatly streamlined the rescue archaeological research of the relics of the anti-aircraft defense firing position from the 2nd world war.
