3. Tunnel fire has its own features and is very dangerous. FBG tunnel fire detection system was selected according to the characteristics of tunnel fire. 随道火灾有其自身特殊性并且危害很大，根据隧遗火灾的特点选用光纤光栅隧道火灾探测系统；
4. Using the ultrasonic wave detector to probe the flexible range of the extraction tunnel, grasping the rule of deformed tunnel directs the supporting design of the tunnel bolt. 利用超声波探测仪探测回采巷道的松动范围，掌握巷道的变形破坏规律，以此指导巷道的锚杆支护设计。
5. Engaged in relevant tunnel work for 33 years, he managed the construction of Hsueh Shan tunnel, by taking responsibility of breakthrough of pilot tunnel and two main tunnels. 从事隧道相关工作33年，并主持雪山隧道工程施工，负责导坑与两条主隧道施工与贯通。
