摘要
通过分析高原煤矿所处环境大气压力、氧分压及氧含量随海拔高度的变化规律,得到高原矿井作业人员的血氧饱和度及最大做功量与海拔高度的关系,确定出不同海拔高度下煤矿工人每天所允许的最大能耗值。对比不同海拔高度下高原养路工的最大做功量,得出高原煤矿工人不超过自身最大能耗值的临界海拔高度,即目标海拔高度。通过理论计算,得出目标海拔高度下的环境参数;从人员的适应性入手,确定目标海拔高度的合理性。研究结果表明:大气压力、氧分压、氧含量、人体血氧饱和度及最大做功量随着海拔高度的增加而降低;高原煤矿工人生产的适宜环境的目标海拔高度为+2 700 m。
By analyzing the change rule of the environmental atmospheric pressure,oxygen partial pressure and oxygen content of the plateau mine with its altitude,the relation of the saturation of blood oxygen and the maximum work done amount with the altitude was obtained,and the maximum allowable energy consumption value of the coal miners per day at different altitudes was determined. Through the comparison with the maximum work done amount of the plateau road maintenance workers at different altitudes,the critical altitude which did not exceed the maximum energy consumption value of the plateau coal miners was got,namely the target altitude. The environmental parameters at the target altitude were derived by theoretical calculations; starting from the adaptability of the plateau persons,the reasonableness of the target altitude was determined. The research results showed that the atmospheric pressure,the oxygen partial pressure,the oxygen content,the saturation of blood oxygen and the maximum work done amount decreased with the increase of the altitude; the environmental target altitude suitable for plateau coal miners to work was ＋ 2 700 m.
