摘要:
铁路隧道在施工开挖过程中判定具有煤与瓦斯突出危险性，会导致投资增加和工期延长等问题。本文解读了国家煤矿安监局煤安监技装〔2019〕28号文附件《防治煤与瓦斯突出细则》与TB10120-2019《铁路瓦斯隧道技术规范》中关于煤与瓦斯突出危险性判定的规定。通过对比不同铁路隧道煤与瓦斯突出危险性判定实例，讨论了铁路隧道各阶段煤与瓦斯突出危险性判定的原则。研究发现：勘察阶段钻孔内瓦斯测试数据欠准确的原因主要包括：（1）钻孔内测试深度与施工揭示煤层的深度不一致；（2）钻孔内煤层深度过大影响测试准确性。
Abstract:
Identification of coal and gas outburst hazard during excavation for railway tunnel can lead to increased investment costs and extended construction timelines. This paper interpreted relevant content regarding the determination of coal and gas outburst hazard from the“Detailed Rules for Prevention and Control of Coal and Gas Outbursts，”the attachment of the Document Mei An Jian Ji Zhuang〔2019〕No. 28 issued by the National Coal Mine Safety Administration. It further analyzed related requirements for assessing coal and gas outburst hazard stipulated in TB 10120 -2019“Technical Code for Railway Gas Tunnels”issued by the National Railway Administration. By examining comparative case examples of coal and gas outburst hazard assessments in select railway tunnels，the study discussed the principles guiding such assessments across various stages of tunnel development. In the exploration stage，reasons for the inaccuracy of gas data obtained from borehole testing include：（1）inconsistency between the test depth within the borehole and the actual coal seam depth exposed during construction，and（2）excessive coal seam depth within the borehole compromising test precision.
