Bergamt

A Bergamt or mining office is a mining supervisory authority in German-speaking countries below the level of the state. It exercises immediate supervision of all activities, facilities and equipment associated with mining within a mining district. This includes the promotion and monitoring of operational safety and workplace safety.

 * Stralsund Mining Office (Bergamt Stralsund) for Mecklenburg-Western Pomerania
 * Arnsberg Regional Authority (Bezirksregierung Arnsberg), office in Dortmund, previously Landesoberbergamt Nordrhein-Westfalen in Dortmund

Austria
In Austria it used to be the Berghauptmannschaft until the Mineral Raw Material Act came into force on 1 January 1999, when that was replaced by the Montanbehörden.

Netherlands
In the Netherlands, state supervision of mining is carried out by the Staatstoezicht op de Mijnen (SodM). An important role is its oversight of oil extraction in the North Sea.
