本文介绍了利用寿命表法与相关回归法相结合的方法,对某矿接尘作业工人矽肺发病情况进行了分析,给出了将矽肺累积发病概率控制在一定水平下的最大允许作业粉尘浓度,进而估算出不同的实际已接尘工龄的工人继续接尘时的预期矽肺发病年限。其方法与原理亦可用于其它有害作业防护措施的制订与评价。 This paper introduces the method of combining the life table method with the correlation regression method to analyze the incidence of silicosis in workers exposed to dust in a mine and gives the maximum allowable working dust concentration for controlling the cumulative incidence of silicosis to a certain level. Estimates of the expected life-years of silicosis when different workers actually exposed to dust have continued to receive dust. The method and principle can also be used for the formulation and evaluation of other harmful protective measures.
