The total number of working mines reported in 1982 was 5510. Out of that 516 are coal mines and the remaining 4994 in the non-coal sector. The visual impact of mining on land is the aesthetic damage due to disfiguring of landscape. Opencast/Surface Mining Impacts:
Sep 09, 2014 · BATEA was defined as the model effluent management and treatment system for chloride, bulk metals, ammonia, and TSS removal. Review of the coal sector included a total of 16 operations. In the model effluent treatment system for the sector, bulk TSS is removed via pond-based settling and polishing which may be aided by the addition of flocculant
Sep 06, 2018 · Bioprocesses were developed to evaluate the potential of duckweed (Lemna minor) to treat coal washery effluent (CWE) as well as to study the impact on the biochemical changes of the Lemna minor. CWE samples were diluted with distilled water (DW) in different ratios as follows: T1‐CWE:DW(20:80%), T2‐CWE:DW(40:60%), T3‐CWE:DW(60:40%), T4‐CWE:DW (80:20%), T5‐CWE …
