摘　　要：非煤地层瓦斯涌出量的评估目前还没有系统的理论和方法。通过应用《铁路瓦斯隧道技术规范》(TB10120—2002)和《铁路工程不良地质勘察规程》(TB10027—2012)中煤层瓦斯涌出量计算公式,结合现场瓦斯测试及浓度监测,认为若相关参数取值合理,公式应用于非煤地层是可行的,且规范计算结果更符合客观实际;同时,现场瓦斯浓度检测也是必要的。At present, no systematic theory and method can be used for evaluating the gas emission quantity in non-coal stratum. Therefore, in this study, the gas emission quantity calculation formulas in coal seam were employed, which are stipulated in Technical Code for Railway Tunnel with Gas （ TB10120-2002 ） and Code for Unfavorable Geological Condition Investigation of Railway Engineering （TB10027-2012）, combined with field test and gas concentration monitoring. The research conclusion can be drawn as follows：for non-coal stratum, the use of above-mentioned formulas will be feasible if the relevant parameters are reasonably selected; the calculation result obtained from Technical Code for Railway Tunnel with Gas are even more in accordance with the objective reality; at the same time, it is necessary to test the gas concentration in field.
