Abstract– Extraction of Mineral resources brings internal and external benefits to the country. Coal mining also generates revenue and creates employment. But a big cost is being paid to these mining activities in terms of vegetation clearance. The volume of dust released by coal mining degrades the soil supporting the plant. It impairs the photosynthetic and fruiting ability of plants. In this study biodiversity indices were employed to investigate the effects of mining activities on the vegetation composition within the mining area and 5 km away from mining site. A total of 84 individual belonging to 34 families were recorded in the study. In which 57 individuals belonging to 24 families were found growing in the overburden dump area. Among these 20 trees, 17 shrubs and 42 species were encountered. Shannon and Simpson Diversity Index, Margalef species Richness and Pielou’s species evenness index were also found to be more at unmined area than in mined area.
