As the percentage of shifts in hot working conditions in German Coal mines had increased to more than 50% during the last decade, a study was carried out to record the physiological strain of miners. Thirty-eight miners participated during 125 shifts. Heart rate and rectal temperature were measured continuously. Sweat losses as well as food and fluid uptake were estimated from measurements before and after shifts. During all shifts mean heart rates resulted in 102.8 min(-1), mean rectal temperature was 37.7 degrees C. Mean sweat loss per shift was 3,436 g; mean sweat rates resulted in 494 g/h. Rehydration during the shift at high climatic stress decreased to about 60% of sweat losses. In order to state the organizational frame of work at hot working places in German coal mines, the main features of regulations of work at hot working places are presented.
在过去十年中，德国煤矿高温作业班次的比例已增至50%以上，因此开展了一项研究来记录矿工的生理应激情况。38名矿工参与了125个班次的研究。连续测量心率和直肠温度。根据班次前后的测量数据估算出汗液流失以及食物和液体摄入量。在所有班次中，平均心率为102.8次/分钟，平均直肠温度为37.7摄氏度。每班平均汗液流失为3436克；平均出汗率为494克/小时。在高气候压力下的班次中，补液量降至汗液流失量的60%左右。为了说明德国煤矿高温作业场所的工作组织框架，本文介绍了高温作业场所工作规定的主要特点。
