图山寺高瓦斯隧道综合施工技术

Comprehensive Construction Techniques for the Tushansi Gas-Rich Tunnel

结合图山寺隧道施工中瓦斯燃烧的必要条件,从"降低洞内瓦斯浓度,尽量减少热源,降低热源的温度"的角度出发,采取"禁绝火源、及时预报、排堵结合、及时封闭、强化通风,降低浓度"等配套施工技术,建立和健全了安全制度,制定并切实落实了相关安全措施,取得了高瓦斯隧道施工的完全成功,可为类似工程借鉴。

The following measures were taken to address the condition of gas burning during the construction of the Tushansi tunnel： prohibition of the combustion source; a combination of releasing and blocking; timely closing; enhanced ventilation and reduced gas concentration, heat source, and temperature in the tunnel; and establishment of corresponding safety systems. These measures allowed for the successful completion of the excavation of this gas-rich tunnel.
