[Evaluation of effects of dust prevention in the principal tungsten mines in Jiangxi].
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%.
