我局各野外队施工坑道的海拔高度一般均在3500～5000米。坑道装、载、运作业是整个坑道掘进生产过程中繁重工序之一，它消耗的劳动量占整个掘进循环的30—50％。因此，提高坑道掘进水平，加速地质勘探，改善这一工序的机械化程度有着重要意义。青海高原由于海拔高，空气稀薄缺氧，多数人有高山反应，也有人根本不能适应。普遍问题是劳动效率低或多病，如何解决此问题呢？水电部75年概算指标中曾提到“海拔高度1500～2500米人工机械指标增加10％，2500～3000米增加15％，在我省煤炭部门，也曾对热
I Bureau of the field team construction pit elevation are generally 3500 ~ 5000 meters. The installation, loading and unloading of tunnels are one of the heavy processes in the entire tunneling and tunneling. The amount of labor it consumes accounts for 30-50% of the entire tunneling cycle. Therefore, it is of great significance to improve the level of tunneling, speed up geological exploration and improve the mechanization of this process. Due to the high altitude in Qinghai Plateau, the air is thin and oxygen deficient, most people have alpine reactions, and others can not adapt at all. The general problem is labor efficiency is low or sick, how to solve this problem? Ministry of Water and Electricity 75-year estimate of indicators mentioned in the "1500-2500 meters above sea level index of artificial machinery increased by 10%, 2500 ~ 3000 m increase of 15% in the coal sector in our province, have also been hot
