Abstract

This report presents a chronological overview of the status of respirable dust exposures in underground and surface bituminous coal mines since inception of the 1969 Federal Coal Mine Health and Safety Act. Data for various intervals from 1970 through 1977, are presented for selected mining operations. Comparisons are made using data available from the mine operators' sampling program and from MSHA surveys. The data demonstrate the marked decrease that has occurred in respirable dust exposures since inception of the 1969 Act.

摘要

本报告按时间顺序概述了自1969年《联邦煤矿健康与安全法》颁布以来，地下和露天烟煤矿中可吸入粉尘暴露的状况。报告给出了1970年至1977年不同时间段内部分采矿作业的相关数据。通过矿山经营者采样计划和矿山安全与健康管理局（MSHA）调查所获数据进行了对比。数据表明，自1969年该法案颁布以来，可吸入粉尘暴露量已显著下降。
