communities have been particularly exposed to the detrimental effects of contamination arising from mining and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left thousands of sites in Africa contaminated by mining and associated mine dumps such as tailings and slag material.
In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact. Mining in the karst can lower the water table, which removes the support of rock that overlies water-filled caverns, which can create
