With the planned increase in coal production, more and more land is being brought under mining operation. This result in drastic changes in land use patterns, as mined lands, prior to mining operations, may have been used for forestry, agriculture and any other productive purpose. The most serious impact of mining is the land degradation. Besides, serious impacts of coal mining are impact on top fertile soil, microbial population, heavy metal toxicity, ecology and vegetation, habitat destruction and degradation of ecosystem as a whole. The mine spoils or overburdens created during opencast mining are devoid of nutrients and have low water holding capacity. These are chemically, physically and biologically unstable.
In the present study, an attempt has been made to assess the changes on nutritional and microbial characteristics brought about by afforestation on overburden dumps of coal mine spoil at Jhingurda, Singrauli (M.P.). Different years overburden plantations raised by Madhya Pradesh Forest Development Corporation has been undertaken for study. For comparison, age series of plantations raised on adjoining areas outside the overburden dumps (mentioned as plain plantations) have been studied on the same attributes. The results were found encouraging with respect to amelioration of sites undertaken for rehabilitation activity.
