Abstract
Mining subsidence is ground movement caused by mineral extraction. In most cases, this movement extends to the ground surface. This Standard sets out the steps which must be taken to establish whether mining subsidence is likely to occur at a particular site and explains how the possible magnitude of the movements may be predicted. For structures located where the movements may be significant, this standard outlines the design and detailing requirements to minimise the effects.
