ABSTRACT
The present investigation was undertaken to understand and estimate the impact of opencast coalmining on soil available micronutrients in cultivated soils of Telangana state. Soil samples were collected from Srirampur (Adilabad), Medipalli (Karimnagar), Bhupalapally (Warangal) and Yellandu (Khammam) opencast areas of Telangana. At each opencast mining place surface samples (0-15 cm) depth were collected. 10 surface samples at a distance of 1.5 km (approximately) from opencast coal mining area and another 10 surface soil samples from 3.5 km from coal mines in all directions. These samples are designated as samples within 2 km from coal mining and beyond 2 km respectively. With an assumption that accumulation of coal dust will be within 2 km from mining site. Thus a total of 80 samples were collected i.e 40 within 2 km another 40 beyond 2 km from mining area from four places of opencast i.e Srirampur, Medipalli, Bhupalpally and Yellandu. The data was analysed statistically by two sample t test to compare Zn, Cu, Fe and Mn contents in samples within 2 km and beyond 2 km from opencast coal mining. There was significant change in manganese content of soils within 2 km and beyond 2 km of the mining activity. There was no significant change in zinc, copper and iron content of soils within 2 km and beyond 2 km of the mining activity
Key words: Micro Nutrients, Opencast, Coal Mine.
