LGRB-BW RAW: Raw material extraction in open pit mining (points)

The collection points entered in the database have a unique name (operation ID), which consists of the TK25 sheet number and a serial number (archive number, Arnum for short). This means: (1) Arnums up to and including 99: Extraction sites that have been collected since the mid-1980s as part of the raw material protection concept. (2) Arnums from 100 to 299 inclusive: Extraction sites collected in the 1950s. (3) Arnums from 300: Extraction sites which had already been dismantled before the mid-1980s. The survey is carried out by the raw material geologists of Ref. 96 in the terrain (usually in connection with the processing of a KMR50). Legal and high value of the extraction site refers to the location of the balance – if there is no balance available to the main access point of the extraction site – in the case of old mining, the centre of the extraction site is also often indicated.
