摘要
根据高原的特殊情况,分析了O2,CO2和一些有害气体浓度对人体的影响,探讨了金属非金属矿山安全规程在高海拔地区的适用问题。在2000m以上的高原,建议用等效海拔高度来设定最低O2浓度,并推出了等效海拔高度公式;人体对CO2的分压敏感,用质量浓度表示接触限值在高原地区能够满足要求;对于一些有害气体,建议按海拔细分其接触限值。
In light of the special plateau conditions, the effect of O2, CO2 and other harmful gases on human body is analyzed and the applicability of ＂Safety Rules for Metal and Non-Metal Mines＂ to the high altitude areas discussed. For areas above 2000m, it is suggested to use the equivalent altitude for setting the minimum concentration of O2, and the formula for equivalent altitude is proposed. In respect to the human body＇s sensitivity to partial pressure of CO2, the exposure limit expressed by mass concentration can satisfy the requirement. For some harmful gases, it is suggested to classify their exposure limits based on altitude.
