The aim of this paper is to find out the percentage of airborne dust (-37 micron size) and respirable dust (-71 micron size of U.D.S) causing lungs diseases, in drilling gummings produced during drilling holes in a coal seam. Eleven samples were analysed from different coal seams. It was found that on an average, about 125.8 gms and 32.1 gms of airborne and respirable dust are produced respectively per meter drilled (of diameter 45 mm) in a coal seam. Considering 1% of those dusts becomes airborne, about 320 mg of respirable dust gets airborne per meter of hole drilled in a coal seam.
