It is general recognized that fatigue due to physical overload is a crucial factor resulting in the industrial accidents which seriously threaten the safety and health of miners. Based on the investigation of current situation of miners＇ overload and tendency of accidents at work, the potential influence of fatigue to accidents is analyzed . For field research purposed only heart rate has been estimated as a reliable evaluation technique to assess physical workload the technique became practical suitable and for this study the SWISS equipment BHL 6000 has been used extensively in the underground. Accident material within five years was investigated. This study showed that the risk of accident may increase in fatigue status. If different causes of accidents and the interrelations among them are studied by means of ergonomics and reduction of physical workload to prevent fatigue is used as one of basic contents for management of occupational safety and health it may be very useful to prevent accidents and promote safety in production.
