为验证职业病致残程度鉴定标准及修订标准提供依据，本文采用减少主观指标，增加尘肺期内分级、胸片肺气肿间接征象、心电图、动脉血气分析等客观指标的方法，对１５７９例煤工尘肺进行鉴定。结果：Ⅰ期尘肺致残八级的８４．２１％，五级的１５．７９％；Ⅱ期尘肺致残六级的５４．２２％，五级的４０．６６％，三级的５．１２％；Ⅲ期尘肺致残三级的９６．１５％，二级的３．８５％；尘肺合并结核致残三级的９４．４４％，二级的５．５６％。标准是简单可行的，但仍感在致残等级上分级跨度大；Ⅲ期起步点较高；尘肺合并结核的致残等级不详。对此，我们提出每期尘肺应设三个致残等级的建议。
In order to verify the identification standards and revision standards of occupational disease disability, this paper adopts the methods of reducing subjective indicators, increasing the classification of pneumoconiosis, indirect signs of emphysema of chest radiograph, ECG, arterial blood gas analysis and other objective indicators. Pneumoconiosis identification. Results: 84.21% of stage Ⅰ pneumoconiosis was disabled, 15.79% of stage 5, 54.22% of stage Ⅱ of stage Ⅱ pneumoconiosis, 40.66% of stage 5, 5.12 %; Stage Ⅲ pneumoconiosis was 96.15%, stage 2 3.85%; stage 4 pneumoconiosis with tuberculosis 94.44%, stage 2 5.56%. The standard is simple and feasible, but still in the grading scale on the degree of disability large; higher starting point of stage Ⅲ; pneumoconiosis combined tuberculosis disability level unknown. In this regard, we propose that three levels of disability should be set for each stage of pneumoconiosis.
