An evaluation of the effects of dust prevention in the Jiangxi tungsten mines has been carried out. The rate of silicosis morbidity in most mines was under 1%. Up to 1983, the rate in individual mines is 1.95%. According to the data from those mines, the forecasting of cumulative probability of morbidity of mine workers having been in contact with dust for 30 years is up to 7.5%. From those data, the authors suggest that the maximum permissible concentration of dust should be 1.0 mg/m3 in the mines with concentration of silicon dioxide dust over 70%.
对江西钨矿防尘效果进行了评估。多数矿山矽肺病发病率在1%以下。截至1983年，个别矿山发病率为1.95%。根据这些矿山的数据，对接触粉尘30年的矿工发病累积概率预测高达7.5%。根据这些数据，作者建议，二氧化硅粉尘浓度超过70%的矿山，粉尘最高允许浓度应为1.0毫克/立方米。
