摘　　要：在暗挖隧道盾构法施工中,低瓦斯工区是隧道穿越煤矿采空区所产生的重大施工风险源点。为了适应低瓦斯隧道工区安全施工需求,对盾构瓦斯气体检测、二次风机、应急照明等关键系统进行针对性设计,并提出瓦电闭锁、风电闭锁以及应急照明综保的设计思路,确保盾构施工过程中的作业安全。In the shield construction of underground tunnel,low-gas work area is a major construction risk source caused by the tunnel passing through goaf of coal mine.In order to meet the needs of safe construction in the low-gas tunnel work area,key systems such as shield gas detection,secondary fan and emergency lighting are designed,and design ideas of comprehensive protection of gas interlocked circuit breaking,wind interlocked circuit breaking and emergency lighting are proposed to ensure the operation safety in the process of shield construction.
