Abstract: As an increasing number of mining operations approach closure, criteria by which to measure the success of rehabilitation efforts have become increasingly important and several workers have developed ecosystem success indicators (Tongway et al., 1998; Ludwig et al., 2003; Nichols et al., 2005; Grant, 2006). Mined land rehabilitation as ongoing process designed to restore the physical ...
Oct 24, 2012· In Ghana, the process of small scale mining is said to have rendered some lands unsuitable for any other purpose as a result of uncovered pits many of which are filled with stagnant water thereby serving as breeding grounds for malaria-infected mosquitoes (Aryee et al. 2003), and these have serious negative health effects on people in mining ...
