This document specifies the design loads and the design procedures for the design of structures used in underground mines. This standard covers all steel and concrete structures used in underground mines, irrespective of the depth of the mine or the product being mined.<\/p>\n

This document adopts a limit states design philosophy.<\/p>\n

There are many reasons, based on mining processes, mining equipment, technical, timing, and cost factors why certain structures can be constructed underground for a particular application rather than on surface, and these are carefully assessed at feasibility stage of any mining project. This standard does not set out to provide comments or recommendations regarding the advantages and disadvantages of using any type of structure underground, but it covers specific design aspects considered when using structures in underground mines. This standard is thus primarily intended to provide the technical information necessary to ensure good engineering of structures where their construction and use underground is the chosen solution.<\/p>\n

Typical underground structures covered by this standard include, but are not limited to:<\/p>\n
