隧道瓦斯监测体系优化设计与安全管理分析

The Scheme Optimization Design and Security Management Analysis of Tunnel Methane Monitoring System

以山西某隧道工程瓦斯监控为例,采用人工检测和自动监控相结合建立瓦斯实时动态检测网络体系,并对检测部位和仪器布置方案进行优化设计,针对不同监测部位采用分级管理,实现人机交互预警。对人工检测数据和自动监控数据分析得出瓦斯浓度变化规律,为施工作业安全进行提供数据保障,最后针对不同部位瓦斯超限提出应急处理方案,保障安全。这种人机协同相互补充的瓦斯监控系统可为类似工程提供借鉴。

This article took a methane monitoring project of tunnel engineering in Shanxi province as an example to conduct a research. It established real - time dynamic methane testing network architecture system which concluded manual inspection and automatic monitoring. Then it proposed an optimized scheme of the detection site and instrumentation arrangement and used hierarchical management of different monitoring sites in order to achieve human - computer interaction warning. The variation of methane concentration could be summed up to provide data guarantee of safety construction work. Finally, the emergency scheme of methane concentration gauge has been proposed to ensure the construction safety. This monitoring system which achieved human - machine cooperation mutually complementary can be treated as a model in similar engineering.
