Environmental Reclamation Practice in a Brazilian Coal Mine -- An Economical Approach

Coal mining reclamation is a worldwide concern. This paper presents a Brazilian example where the economic aspects of reclamation are considered. The basic goal of the study is to transform the reclamation procedures into an economic process by integrating the use of land after reclamation and developing profitable post operations. Some of the activities considered in this case study include: 1. using of the coal pit as a landfill, considering appropriate landfill design and construction; 2. using the area for forest development; and 3. developing grassland, forests of native species and the construction of ponds for fishery. This study will conclude that the mined area is: 1. capable of storing large quantities of waste at a competitive cost and at a low environmental risk; 2. commercial forest development is economically feasible; and 3. the lakes and other reclaimed areas can be integrated into the landscape creating a fresh water supply and an area to raise cattle.
