Research on Ozygen-increasing Ventilation in Alpine Region
Lower oxygen pressure of alpine region will bring about a series of influences on the mining activities, it will decrease the oxygen pressure in the air directly, then reduce the ability for hemoglobin to contain oxygen capacity, and caused the human body lack of oxygen, such as hypoxic altitude reaction, therefore it is necessary to use oxygenintensive ventilation. Based on the underground ventilation characteristics of alpine region, this paper discusses two methods of through the ventilation system to increase underground oxygen partial pressure in alpine region: Increase oxygen percentage of air by oxygen production at rooM temperature and the use of forced ventilation increase atmospheric pressure, as well as their realization, and to compare and analyze their own characteristics, provide the basis for underground ventilation in alpine region.
