摘　　要：选取某高原矿山掘进掌子面矿工进行弥散式增氧、背负氧气瓶呼吸面罩增氧和不增氧测试,在氧气增补的同时矿工照常工作。设计了掌子面弥散供氧系统,设定了4项生理指标和8项观察指标用于氧气增补效果的定性及定量分析。进行弥散增氧后,掌子面附近氧分压发生改变,得到氧分压分布曲线。利用生理指标和观察指标对高原矿山氧气增补效果进行综合探讨,结果表明:氧气增补能够有效地提高作业人员的血氧饱和度,降低脉率和每分钟呼吸次数,明显改善人体不适症状,增强人体生理机能;综合来看,弥散式增氧方式更加适用于高原矿山氧气增补。Selected heading face miners of a plateau mine with oxygen supplementation of diffusion, with oxygen sup- plementation of carrying oxygen bottle with breathing mask and without oxygen supplementation, in addition to oxygen sup- plementation the miners worked as usual. Designed face oxygen supply system of diffusion, while set 4 objective signs and 8 observation signs for qualitative and quantitative analysis the effect of oxygen supplementation. The partial pressure of ox- ygen had changed after face oxygen supplementation of diffusion, and drew the distribution curve of it. Using objective signs and observation signs to comprehensive study on the effect of oxygen supplementation for plateau mine, the results show that oxygen supplementation could improve the oxygen saturation, reduce the pulse rate and the number of breaths per minute of tunneling workers ; physiological function of human body enhanced, body discomfort symptoms obviously improved; in gen- eral, oxygen supplying way of diffusion was more suitable for oxygen supplementation of plateau mine.
