The height of the overburden dumped wasabout 20 meters.The management has not carried out monitoring of air,water and noise.The mine has been in operation for about 17 monthsand no afforestation is carried out in the mine–out area.A seasonal approach road measuring about 3 km takesofffrom Daurpani industrial area.There was no side and cross drain to channel thesurface water.The progressive restoration was focused only onconstruction of check dams.Environment Bond deposited Nu. 1,44,000.07. Others On either side of the mine there were settlements;resettlement on the left and Bahundara village on theright. The aerial distance was about 50 to 70 meters.A newly constructed farm road passes right below themine.There were some stretches where pocket mining wasdone.The mine-out area had not been restored and was leftto the nature for regeneration.Waste dump-yard was located above the farm road.Overburden spills into Kharikhola basin, which passesthrough the mine.There was no channeling of mine water.1.22 RecommendationThe management has to construct uniform benches and widths as mentioned in the FMFSand EMP including waste dump-yard.Restoration work was not carried out at the mine-out area. The management has to carryout restoration activities for those mine-out areas, instead of letting up to the nature forregeneration.60
