摘　　要：本文根据推导出来的巷道末端风温计算公式,找出影响巷道末端风温的主要因素.进而提出热害矿井主要巷道的合理断面形式和永久支护形式.同时得出结论,热害矿井主要巷道采用喷射混凝土作为永久支护是不合理的.According to infered calculating formula of airflow temperature at the end of tunnel, the main elements influencing airflow temperature at the end of tunnel is pointed out in this paper. And then, the rational form of section and permanent support of primary tunnel in high-temperature mine is put forward. Moreover a conclusion is drawn that adopting shotcrete as the final lining for primary tunnel in high-temperature mine is irrational.
