60年代初,我国煤矿普遍开始了井下防尘工作,近年,防尘效果研究日益受到重视,但煤矿间评价结果差别颇大,原因之一是分析方法不同所致。本文选择三个煤矿,利用各矿历年尘肺普查资料,讨论涉及处理复杂资料的流行病学及统计学问题,期望建立一个切实可行的考核方法,以便全国煤矿的同行对本矿的尘肺防制效果作出评价。
In the early 1960s, coal mines in our country generally started to work underground to prevent dust. In recent years, the research on the effect of dust prevention has been paid more and more attention. However, the results of coal mines vary widely. One of the reasons is the different analytical methods. In this paper, three coal mines are selected to make use of the data of pneumoconiosis survey over the years in various mines to discuss the epidemiological and statistical issues involved in handling complex data. It is expected that a practical assessment method will be established so that counterparts in coal mines can make the pneumoconiosis prevention effect of this mine Evaluation.
