DIN 21906:2017-08

This document has been prepared as part of the series of standards "Mine plans" by Working Committee NA 005-03-05 AA "Markscheidewesen" ("Mine surveying") at DIN Standards Committee Building and Civil Engineering (NABau). According to the Ordinance on Mine Surveying and Surface Observations (Markscheider-Bergverordnung - MarkschBergV), the generally recognized rules of mine surveying and surveying shall be observed for mine surveying and other surveying work in connection with activities and facilities in accordance with Section 2 of the German Federal Mining Act (Bundesberggesetz) - this includes, among other things, the exploration and extraction of non-mineable and underground mineral resources and the associated reutilization of the surface. Compliance with these rules is presumed as long as the "Mine plans" standards are observed. This standard distinguishes between two cases: 1. existing mine workings in the Gauß-Krüger coordinate system (GK) shall continue to be managed on the basis of the sheet division according to the Topographical Overview Map 200 (TÜK 200) or German Base Map (DGK). The subdivision of sheets for the general maps at a scale of 1 : 10 000 are specified in Supplements 1 and 2 to this standard. For the sheet layout based on the DGK, no sheet layouts have been added. In order to make a distinction on the basis of the sheet designation, the sheet name is placed above the coordinates for the division according to TÜK 200, whereas the sheet name is placed below the coordinates for the sheet division according to the DGK. In addition to the GK coordinate system, the UTM coordinate system (Universal Transverse Mercator Coordinate System) is specified. 2. Regulations for a variable sheet intersection have been created for the production of new mine plans and the transformation of existing mine plans into the UTM coordinate system.
