To prevent the risk of abnormal gas emissions during tunnel excavation through unstable coal-bearing strata, this study focused on the inclined shaft section of Baoanying No.1 Tunnel in the Chengdu-Kunming Railway Expansion Project. Through on-site monitoring, numerical simulation, and engineering application, gas emission patterns, risk identification methods, and prevention technologies were investigated. The results indicate that tunnel gas originates from unstable coal seams and carbonaceous rocks within the strata, and gas emissions correlate strongly with coal/carbon content in surrounding rocks and the degree of geological fracturing. Then an integrated geophysical-geological drilling approach was employed to establish an advanced identification method for abnormal gas emissions. This method utilizes multiple indicators: unfavorable geological bodies, lithological variations, borehole gas concentrations, and emission rates. A "borehole curtain" interception technique was developed for high-efficiency gas risk prevention and control. Boreholes arranged in curtain patterns were drilled from both side chambers to intercept and extract coal-rock gas ahead of the advancing tunnel face. Field applications demonstrate that this technology reduces construction interference and increases advance rates.

为治理非稳定含煤地层条件下隧道瓦斯异常涌出风险,以成昆铁路扩改项目保安营1号隧道1号斜井工区为对象,通过现场测试、数值模拟和工程试验相结合的方法,研究瓦斯涌出特征、异常涌出风险判识方法及防控技术。结果表明:隧道瓦斯源于洞身穿过地层中的不稳定煤层、碳质岩,围岩含煤、含碳情况及地质体破碎程度与瓦斯涌出息息相关;可采用物探+钻探综合测试方法,以不良地质体、岩性变化、钻孔瓦斯体积分数及涌出量作为多元辨识指标,确立瓦斯异常涌出超前判识方法;针对非稳定赋存瓦斯异常涌出风险,提出“钻墙”高效截流防治技术,在隧道两侧钻场内施工围绕掘进隧道的“钻墙”钻孔,抽截煤岩瓦斯。现场应用结果证明:此方法有助于减少施工干扰,提高进尺速度。

为治理非稳定含煤地层条件下隧道瓦斯异常涌出风险,以成昆铁路扩改项目保安营1号隧道1号斜井工区为对象,通过现场测试、数值模拟和工程试验相结合的方法,研究瓦斯涌出特征、异常涌出风险判识方法及防控技术。结果表明:隧道瓦斯源于洞身穿过地层中的不稳定煤层、碳质岩,围岩含煤、含碳情况及地质体破碎程度与瓦斯涌出息息相关;可采用物探+钻探综合测试方法,以不良地质体、岩性变化、钻孔瓦斯体积分数及涌出量作为多元辨识指标,确立瓦斯异常涌出超前判识方法;针对非稳定赋存瓦斯异常涌出风险,提出“钻墙”高效截流防治技术,在隧道两侧钻场内施工围绕掘进隧道的“钻墙”钻孔,抽截煤岩瓦斯。现场应用结果证明:此方法有助于减少施工干扰,提高进尺速度。

To prevent the risk of abnormal gas emissions during tunnel excavation through unstable coal-bearing strata, this study focused on the inclined shaft section of Baoanying No.1 Tunnel in the Chengdu-Kunming Railway Expansion Project. Through on-site monitoring, numerical simulation, and engineering application, gas emission patterns, risk identification methods, and prevention technologies were investigated. The results indicate that tunnel gas originates from unstable coal seams and carbonaceous rocks within the strata, and gas emissions correlate strongly with coal/carbon content in surrounding rocks and the degree of geological fracturing. Then an integrated geophysical-geological drilling approach was employed to establish an advanced identification method for abnormal gas emissions. This method utilizes multiple indicators: unfavorable geological bodies, lithological variations, borehole gas concentrations, and emission rates. A "borehole curtain" interception technique was developed for high-efficiency gas risk prevention and control. Boreholes arranged in curtain patterns were drilled from both side chambers to intercept and extract coal-rock gas ahead of the advancing tunnel face. Field applications demonstrate that this technology reduces construction interference and increases advance rates.
