Generally used as permanent passive support away from the working face and on gullies to provide areal coverage in the stope. Examples are chock packs, modular mat packs, C-Packs, Spaced mat packs, end grain mat packs, timber composite mat packs and brick composite mat packs. Commonly used in deep level gold and platinum mines.
Generally used in shallower gold and platinum mines where conditions allow. Elongate support can vary from basic mine poles, which allow minimal deformation to more sophisticated designs of pencil props, Saturn props and other higher yielding elongates, with design yielding of up to 400mm and beyond.
