目的：对玻璃生产原料开采和加工粉尘作业工人尘肺发病水平进行预测，为制定有效防护措施提供科学依据。方法：应用寿命表法求得接尘剂量与发病水平的关系。结果：发病水平随接尘剂量的增高而增高，求得了两者之间的回归方程。结论：如果把发病概率控制在５％以下时，在粉尘浓度１ｍｇ／ｍ３的条件下，工作年限不应超过３７年；如控制在２ｍｇ／ｍ３，工作年限不应超过１８．５年。
OBJECTIVE: To predict the incidence of pneumoconiosis in mining and processing of dust-producing workers in glass production and provide a scientific basis for the formulation of effective protective measures. Methods: Using the life table method to get the relationship between dose and incidence of dust. Results: The incidence of disease increased with the increase of dusting dose, and the regression equation was obtained. Conclusion: If the probability of incidence is controlled below 5%, the working life should not exceed 37 years under the dust concentration of 1mg / m3; if the control is at 2mg / m3, the working life should not exceed 18.5 years.
