Abstract：Seven particle size fractions of Jinjitan pulverized coal samples were screened using sieve shaker and different aperture sieve.Experimental study on explosive test of pulverized coal samples was carried out.The results proved that pulverized coal explosiveness became weak gradually with the increase of particle size and became non-explosive at last;the explosiveness had been significantly reduced when granularity increased to 0.102 mm~0.125 mm and became non-explosive when granularity increased to 0.15 mm~0.25 mm.
