dc.description.abstract Coal mining is a mature industry and plays a vital part in the economy and development of South Africa. Coal mining however is a temporary use of land. Historically, when an ore body was exhausted, production ceased and mines were boarded up and abandoned. Today mine closure requires the return of land to a viable and sustainable post-mining land use but a number of challenges are associated with mine reclamation. One of the greatest challenges is the inability of mines in South Africa to return mined land to its pre-mining state or land capability. The minimization of loss of land use capability and equally soil resource is a key part in achieving success in mine reclamation. This study verifies and assesses the replaced soil depth and actual post-mining land capability at a surface coal mine in Mpumalanga province, according to the Chamber of Mines “Guidelines for the rehabilitation of mined land” (2007). Five of the seven reclaimed sites within the study area exceeded the planned land capability proportions determined during the pre-mining stage. A top soil balance done at the end of January 2010 however indicates that the available volume of soil resource at the mine will not suffice the amount needed to achieve the planned land capability in areas not yet reclaimed. It is suggested that the lack of an adequate soil monitoring and management strategy in the past, has led to the shortfall of the available soil resource at the mine. The soil monitoring and reconciliation strategy developed will hopefully assist mine managers and rehabilitation planners to prevent further soil loss at the mine. en_US
