Examination of collapsed pillar cases outside of the empirical limits of Salamon and Munro’s in situ database has highlighted the need for additional parameters to be considered in the design of coal pillars. These include the influence of discontinuities, surrounding strata characteristics and the effects of deteriorating and time. The results of these investigations have been put together to form the basis of a new methodology for pillar design. As a result, a pillar design flowchart has been produced.
