Abstract: In order to promote the cardiopulmonary function and health of miners in plateau areas, this paper uses scientific methods such as questionnaire survey, mathematical statistics and comparative analysis to test the cardiopulmonary function of healthy adult miners in Chian Tyrone, Tibet (high altitude area) and Kailuan, Hebei(low altitude area), and studies the test results from three dimensions of ventilation index, metabolic index and heart rate variability index.The results showed that there were significant differences in ventilation index, metabolism index and heart rate variability index between the plateau miners and the plain miners, and the indexes showed that the cardiopulmonary function of the plateau miners was significantly weaker than that of the plain miners.Based on the above research results, some suggestions were put forward to improve the cardiopulmonary function of plateau miners.This research has certain reference value and significance for improving the health of miners working on plateaus.
