摘要
在调查长江主要煤港2940名装卸工人接尘背景的基础上，用寿命表法推算煤港工人发（煤尘肺）病概率，建立了累积接游离SiO2量和累积发病概率的回归方程．预测了发病率为1％时一生中安全工作的接尘浓度，提出了交通运输行业应执行的煤粉尘环境最高容许浓度值，计算了在不同煤粉尘浓度下发病概率为1％的安全工作年限．
Based on the investigation of working environment at coal harbors for 2 490 loaders, anaccumulated probability of coal pneumoconiosis is calculated by means of life-span tablemethod. Using regression equation, a safe dust contentration for all loader's life and a safeworking time period with different dust concentrations are forecasted under 1 percent probability of falling pneumoconiosis. Meanwhile, the highest allowable coal dust concentrationfor transportation trade is suggested.
