为了探索高温、高温作业对机体影响的主要作用因素,采取有效措施,改善劳动条件,保障工人健康,为生产服务。我们连续两年夏季对湖北省黄石市煤炭局所属深井煤矿作了对比调查研究。研究对象系10名身体健康、年龄在25～35岁、工龄在5年以上中班的采煤工人。我们连续两天随班测定该班工人在改善矿井通风前后的工前、工中和工后的生理变化,作为评价通风效果的依据。测定项目包括:矿井各点的气象条件、劳 In order to explore the impact of high temperature and high temperature on the body of the main factors that affect the body to take effective measures to improve working conditions, to protect the health of workers, for production services. For the second consecutive year, we conducted a comparative study on the Shenjing coal mine owned by Huangshi Coal Bureau of Hubei Province. The object of study was 10 coal miners who were healthy, aged 25-35 years old and had a working age of over 5 years. For two consecutive days, we measured the physiological changes of workers in this class before and after improving mine ventilation before and after the mine ventilation as the basis for evaluating the ventilation effect. Measured items include: mine weather conditions, labor
