我矿是一个具有八十多年历史的老矿,矿岩中游离二氧化矽含量在25～50％之间,现有职工中接触粉尘者约37.5％,作业在两个坑口、三个车间、202个产尘点。几年来,我们在认真贯彻执行中央(70)71号文件和国务院关于防止矽尘危害的决定中,取得了一点成绩。全矿粉尘合格率七一年实测点为56％、七四年提高到应测点的58.9％,目前达到了73.5％,有效地保护了工人的身体健康。全矿五五年以来接触粉尘的职工,经照线胸片多次检查没有发现得矽肺病的。
My mine is an old mine with a history of more than 80 years. The content of free silica in mine rocks is between 25 and 50%. About 37.5% of the employees are exposed to dust, working in two pit mouths and three workshops , 202 dust spots. In the past few years, we have made some achievements in earnestly implementing the document No. 71 of the Central Committee (No. 70) and the State Council’s decision on preventing the harm of silica dust. The passing rate of all-ore dust reached 56% in 2011 and 58.9% in 1974 to 73.5% at present, effectively protecting the health of workers. The mine dust contact workers in five or five years, many times through the chest X-ray examination found no silicosis.
