DetailsAir Quality Management in Mining Areas. To minimize dust generation during mining processes, modern technologies are adopted and regularly monitored – surface miners, fog canons, mist sprayer, wheel washing, mechanised road sweeper, CAAQMS, wet drilling to minimize dust generation. Drill machines are also fitted with dust suppression system.
DetailsAn increase in absenteeism reduces output per man-shift, which raises the production cost. This will affect the mine's overall output. The physical workload and energy expenditure are the most apparent job demand in mining industries. The mine authorities force the mine workers to do their job without significant rest to attain the production ...
DetailsProductivity in mining activity is measured chiefly by output per man shift (OMS) and this reflects how efficiently operations are carried out. The Indian mining sector is unfortunately characterised by rather low OMS levels. ...
