中梁山隧道横穿中梁山背斜，轴部为断层，断层裂隙带下约30m伏有超级瓦斯煤层。隧道拖工通过此断层时有瓦斯喷出（或涌出），为策施工安全，对瓦斯的监控与管理体系、防治瓦斯的作法与安全标准以及施工通风的设计与计算等均做了周密的考虑。实践证明，所有措施是奏效的，未出现瓦斯事故。 The tunnel in Liangliangshan traverses the Liangliangshan anticline with a shaft section of fault and a super-gas seam of about 30m volts under the fault fracture zone. When the tunnel is towed through the fault, there is gas blowout (or gush out). In order to ensure the construction safety, the monitoring and management system of gas, the practices and safety standards of gas prevention and control and the design and calculation of construction ventilation are well-made consider. Practice has proved that all measures are effective, there is no gas accident.
