DIN 21530-2:2016-09

The DIN 21530 series of standards regulates the quality assurance procedure for mine support used in underground mines to secure and keep open the mine workings required for operations. It can also be used for the lining of non-mining underground cavities. Observance of the standards is intended to ensure that the mine support functions as planned in terms of safety and operation, and to enable it to be used economically. DIN 21530-2 specifies the dimensions and limiting dimensions for support systems and support components for mining and their designation. For reasons of better handling of the standard, the static values have been added for the profiled bars. This standard has been prepared as part of the DIN 21530 series of standards "Mine support" by NA 005-05-23 AA "Bergbau; Streckenausbau" ("Mining; Roadway support") at DIN Standards Committee Building and Civil Engineering (NaBau).
