LGRB-BW RAW: Surface extraction of raw materials in operation (points)

The presentation includes the working surface extraction points of the LGRB’s raw material extraction points database. 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). The coloring of the symbols is based on the raw material groups.
