The SIMRAC project COL 021A entitled “a reassessment of coal pillar design procedures” set out to achieve a coal pillar design procedure that takes cognisance of different geological and structural factors as well as the influence of the surrounding strata. Three enabling outputs were defined at the commencement of the project. These were firstly, the determination of the individual seam strength of coal seams in the different coalfields, secondly, a study of pillar foundation failure, and thirdly, techniques and guidelines to ensure safe and stable bord and pillar workings.
