The Difference of Physiological Indicators of Ground and Underground Subway Workers: A Preliminary Field Study

Underground mining has traditionally been one of the most hazardous industries, and various accidents happen with high frequency in recent years, highlighting the need for explicit attention to safety management in the course of industrialization in China. Researchers and practitioners tend to overlook the physical and mental load of the front-line workers, which gives rise to the potential hazard in production. By investigating the workers physiological and psychological states, the research could enlighten management practice including formulating new production plan and reducing industrial hazards caused by fatigue, lagged responsiveness and misreading. The current study adopted physiological measurement techniques to study the differences of subway construction workers' physiological and psychological states between two conditions-on the ground and underground, and contributed to the research on safety management of underground construction projects from human-oriented perspective.
