摘要
瓦斯隧道分类分级对施工、运营安全有着极为重要的影响。首先,分析和对比现行瓦斯隧道规程、规范、指南以及煤矿系统相关规范对瓦斯隧道(矿井)的分类分级和设防标准;然后,总结瓦斯隧道分类分级中存在的问题,提出根据规划、建设、运营阶段掌握的资料深度及工作重点采用三阶段分类分级法,并给出各阶段的分类分级标准;最后,以运营隧道瓦斯环境等级分级为基础,构建瓦斯隧道设防标准,根据设防标准可建立瓦斯设防结构体系,为瓦斯隧道建设和运营安全提供保障。
The classification of railway gas tunnel has a significant influence on tunnel construction and operation.Firstly,the standards of classification and fortification of gas tunnel(mine) in relevant existing rules,codes and guidelines are analyzed and compared. And then,the problems of the classification of gas tunnel are summarized,triplephase classification method is established based on the collected data and working keys of planning phase,construction phase and operation phase,and the classification standards of every phase are put forward. Finally,the classification standards of fortification of gas tunnel is established based on environment classification standards of running gas tunnel;furthermore,the fortification structure system of gas tunnel can be established,so as to guarantee the construction and running safety of gas tunnel.
