１９９０年至１９９６年，对云浮硫铁矿从事连续接尘作业３年以上的职工逐年进行尘肺发病调查。１９９０年全面普查新发的尘肺病达１６例，年平均发病率为１．６‰，是该矿建矿以来检出尘肺最多的一年。为此，预防尘肺便成了该矿职防工作中突出的重要问题。从１９９１年起，该矿进一步加强了劳动卫生管理，使作业点的粉尘合格率从１９９０年的４２．４％提高到１９９６年的９５％；此后，尘肺发病率明显降低，使尘肺发病得到了控制
From 1990 to 1996, workers who engaged in continuous dust collection operations for more than 3 years in Yunfu Pyrite Mine were investigated annually for pneumoconiosis. In 1990, a total of 16 new cases of pneumoconiosis were reported through the comprehensive census, with an average annual incidence rate of 1.6 ‰. This year saw the largest number of pneumoconiosis detected since the mine was established. Therefore, the prevention of pneumoconiosis has become an important and prominent issue in the job prevention work of the mine. Since 1991, the mine has further strengthened labor hygiene management, raising the passing rate of dust at the work site from 42.4% in 1990 to 95% in 1996; thereafter, the incidence of pneumoconiosis was significantly reduced and the incidence of pneumoconiosis was obtained control
