煤矿井下采掘作业环境的气象条件好坏,直接影响工人健康和劳动效率。目前许多煤矿井下采掘作业面的温度很高,有的高达30℃或30℃以上,相对湿度普遍高于85%,高温高湿对采掘工人的健康和劳动能力影响甚大。为此煤炭系统曾专门组织力量研究解决井下作业环境高温问题。改善作业环境温度,需要有一切实可行的卫生标准作为采取工程技术措施的依据,因而我们进行了煤矿井下采掘作业环境气象卫生标准的调查研究。一、内容和方法:
The meteorological conditions of coal mine underground working environment directly affect the workers’ health and labor efficiency. At present, the temperature of many coal mining face is very high. Some of them are as high as 30 ℃ or above and the relative humidity is generally higher than 85%. High temperature and high humidity have a great influence on the health and working ability of the diggers. To this end the coal system has been specially organized forces to study and solve the problem of high temperature downhole operating environment. To improve the working environment temperature, we need to have practical health standards as the basis for taking engineering and technical measures. Therefore, we conducted a survey on environmental meteorological hygiene standards for underground coal mining operations. First, the content and methods:
