deep mine confined space high temperature thermal harm response indexes multivariate linear regression occupational health
To investigate the influence of high temperature in deep mines on human physiology health and work efficiency, the sources causing high temperature of deep mines and the harm to human body were analyzed. The human composite response indicators were selected according to the physiological feature of human body. Based on a simulation equipment of confined space in deep mines, the high temperature environment of the confined space in deep mine was simulated and the physical simulation experiment to test some human response indexes of physical health and work efficiency in high temperature of mines were carried. The data of high temperature simulation test were used to build the prediction model of multivariate linear regression, and the relationship between human body response indexes and temperature were analyzed quantitatively and accurately. The test results showed that temperature has greater influence on blood pressure, heart rate, breathing rate, fatigue, attention and memory, and has the smaller influence on body temperature and human reaction. The prediction models of the related influence degree of the temperature on the indexes were determined. The test results also provide the scientific basis for studying the work hazard in confined space with high temperature in deep mines and for setting the relevant occupational health standards.
