红岩湾隧道横穿废旧煤窑采空区施工安全措施

结合新建高速公路特长瓦斯隧道施工实际情况,从隧道施工进出洞管理、瓦斯超前探测、瓦斯监测、加强通风、机电设备防爆改造、严格管理火源等方面,详细阐述了在隧道横穿废旧煤窑采空区施工过程中采取的诸多安全管理及技术措施。整个隧道施工过程中采取"动态管理、动态施工",有效地保证了各工序施工处于安全受控状态,确保了隧道施工的安全、质量和施工进度。

Construction Safety Measures for Hongyanwan Tunnel across the Deserted Mined-out Coal Field

The paper,through a long gas tunnel construction of newly-built highway,from the perspectives of the gas tunnel portal management,gas advanced detection,gas monitoring,enhanced ventilation,the flameproof transformation of mechanical and electrical equipment,strict management of fire sources,elaborates the safety management and technological measures in the construction of tunnel across the deserted mined-out coal field.dynamic management,dynamic construction used throughout the whole process of tunnel construction effectively ensures the controlled safety state of the construction process as well as the safety,quality and progress.
