- Impacts Of Limestone Mining In Africa
drainage originating from the coal and ore mining processes in general and open-pit mining in particular are well documented in the literature (Cherry et al. 2001; Skousen et al. 2002). Even though the environmental impacts of ore and coal mining have been adequately investigated, the impact of limestone rock mining has not been well studied.

The limestone averages 18.3 m (60 ft) in thickness, with mining planned in two lifts (i.e., initial development and benching). The height of the initial development was 7 m (23 ft). Secondary bench mining removed an additional 9.1 m (30 ft) from the floor, resulting in a total planned mining height of 16.2 m (53 ft).

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 …
