Abstract

tThe extractions of coal through opencast mines and power generation from coal combustion in thermalpower plants pose the concerns of environment due to huge production of overburden and fly ash, respec-tively. Considering fly ash as a soil ameliorant and other amendments as fertility supplement, reclamationof mine overburden and lowland in Jharia coalfield was carried out through plantation of efficient pho-tosynthetic and soil-binder species. The characteristics of minespoil and lowland significantly improved(except N and K), photosynthetic rate and soil conserving efficiency of the planted species enhanced,and concentration of SPM, RSPM, CO2, SOx, and NOxreduced significantly over the control. Among thetree species, Acacia auriculaeformis, Albizia lebbek, Dalbergia sisoo, Cymbopogan flexuosus and Vetiveriazizanoides among the herbaceous plants showed most promising performance in respect of improvingthe physicochemical characteristics of mine spoil, photosynthetic activity and leaf area along with signifi-cantly conserving the soil erosion and water runoff. Thus the overburden and lowland in a coal mining areacan be successfully reclaimed with improved aesthetic view and environment, via selective plantationusing fly ash and other amendments.
