To determine the nature and grade of air pollutants at different locations (work sectors) of the mine and also to find out how to institute improvements.
Air samples at peak working periods were taken three times, to obtain a median value, using a Dräger Quantimeter 1000 with both short- and long-time exposure detection tubes.
Underground tunnels, surface mine, milling department, explosive store, chemical laboratory and other important corners of Kushk Mine, Iran.
Gases supposed to have evolved because of natural ore distribution or gases produced by different mining and milling procedures.
Very high concentration of sulphur dioxide emission (31.5 ppm) on to the surface through the main ventilation window and also high atmospheric levels of carbon monoxide (62 ppm), oxides of nitrogen (50.2 ppm) and cyanides (11.4 ppm) could be detected.
