Construction upon dolomites of the South-Western Transvaal
Abstract Some 15 000 $ km^{2} $ of the Transvaal Province of South Africa are underlain by soluble dolomite rocks. The south-western part of the Province contains some of the world's largest gold mines. Development and operation of these mines has affected performance of surface structures through groundwater lowering in soil covered areas underlain by cavernous dolomite. The geology, climate and landforms of the area are summarized, together with properties of the various chert residuum and manganiferous wad deposits that are often encountered above hard dolomite. Site investigation procedures are described in these areas using remote sensing, gravimetric and trenching or drilling techniques. Various methods of foundation treatment upon dolomites are discussed in detail, with specific attention given to the use of compacted fills. A simplified theory of a two-dimensional compacted soil arch and its support capability is presented. The use of compacted soil to bridge economically between dolomite pinnacles is described in two case histories of mining plant construction. The application of detailed site investigation work to large housing and township development is described in a third case history.
