我国有些矿山井下气温常低于15℃,有些达28℃以上,这些矿井的相对湿度往往在80—90％之间。工人长期处在这样的低温高湿和高温高湿的环境中,从事繁重的体力劳动,对身体是不利的。 目前矿山工人一般发放一套纯棉布工作服,普遍反映在低温时不能防寒,患膝关节疼痛的多,高温时间热,不能防暑。 国外对矿山工作服的研究有不少报道,国内尚未有这方面的报告。
Some of our mine pit temperatures are often below 15 ℃, some up to 28 ℃, the relative humidity of these mines are often between 80-90%. Long-term workers in such a low temperature and humidity and high temperature and humidity environment, engaged in heavy manual labor, the body is not conducive. At present, miners generally release a set of cotton cloth overalls, which are generally reflected in the cold can not be cold, suffering from knee pain, hot heat, not sunstroke. There are quite a few reports on the study of mining overalls in foreign countries. There is no such report yet in China.
