Abstract

OBJECTIVE

To characterize differences in mining jobs and tenure between contemporary (born 1930+, working primarily with modern mining technologies) and historic coal miners with progressive massive fibrosis (PMF).

METHODS

We classified jobs as designated occupations (DOs) and non-DOs based on regulatory sampling requirements. Demographic, occupational characteristics, and histopathological PMF type were compared between groups.

RESULTS

Contemporary miners ( n = 33) had significantly shorter mean total (30.4 years vs 37.1 years, P = 0.0006) and underground (28.8 years vs 35.8 years, P = 0.001) mining tenure compared with historic miners ( n = 289). Silica-type PMF was significantly more common among miners in non-DOs (30.1% vs 15.8%, P = 0.03) and contemporary miners (58.1% vs 15.2%, P < 0.0001).

CONCLUSIONS

Primary jobs changed over time with the introduction of modern mining technologies and likely changed exposures for workers. Elevated crystalline silica exposures are likely in non-DOs and require attention.

摘要

目的

描述现代矿工（出生于 1930 年及以后，主要使用现代采矿技术）和患有进行性大块纤维化（PMF）的历史矿工之间在采矿工作和工龄方面的差异。

方法

我们根据监管抽样要求将工作分为指定职业（DO）和非 DO。比较两组之间的人口统计学、职业特征和组织病理学 PMF 类型。

结果

与历史矿工（n=289）相比，当代矿工（n=33）的平均总工龄（30.4 年比 37.1 年，P=0.0006）和地下工龄（28.8 年比 35.8 年，P=0.001）明显更短。非 DO 中的矽肺型 PMF 明显更常见（30.1%比 15.8%，P=0.03），而当代矿工中的矽肺型 PMF 明显更常见（58.1%比 15.2%，P<0.0001）。
