Even though the percentage contribution of mining in Gauteng to the provincial GDP is relatively low (2.3%) it is a substantial amount (R22.34 billion) and should be viewed against other economic activities in Gauteng, the industrial heartland of South Africa, and the historical importance of gold mining in this province.
the mining operations. The disturbance of the natural environment by the mining industry has triggered the South African government to formulate laws that dictate that miners should pay to remediate the damage they cause. Mine rehabilitation is a long term process which should ideally begin during the planning phase of a development.
the South African narrow reef mining industry has battled to control working costs in a labour-intensive industry. It is only through the application of appropriate technology that change will occur. It is the stoping method that is at the heart of the mining system. Introduce a different technology that results in a more efficient stoping ...
WWF-SA Mining Financial Provisions | page 5 EXECUTIVE SUMMARY Ongoing concerns regarding environmental degradation in mining areas, the high number of ownerless and abandoned mines, and the incidence of acid mine drainage (AMD) have highlighted the need for improved environmental maintenance and rehabilitation in the mining sector.
