The previous searcher of the old showed that one of the most hurmful and dangerous factors coal mines was Air plotion . in other hand we knowthat the dust with certain diameter are dangerous . however the quantity of coal dust it's comparison with standard in the one of mine's mazandaran province was studied . for the search aftwer the point measuring was slots were determined by the usage of sampling pump and cascade impactor that were connected to each them and there was an orifice in bettween them in order to provide a certain amount of flow raite we sampled the rnspiration system of the workers . The findings has determined that the a mount of total dust in the mine was 36 mg per c.m(36mg /m3 ) and from this ' this a mount the concentration of dust with diameter 0.93 to 3.5 micron equal 16.8 per c.m (16.8mg /m3 ). By regarding these results the amount of dust in that mine was a lot mor than it should be and it is few times higher than standard . in order to decrease the dust preventive measure were suggested especially in order to avoid disease .
