摘要
随着新建铁路瓦斯隧道的增多,隧道开挖时穿越突出煤层的可能性也将随之增加,在家竹箐隧道施工中首次运用了煤炭部门所采用的瓦斯预测技术,成功地预测了家竹箐隧道有突出危险的煤层,并运用防突效果检验技术,顺利地揭开石门,安全地通过了煤系地层,为今后修建有煤与瓦斯突出的铁路隧道积累了宝贵经验。
During the construction of Jiazuqing Tunnel . a new technelogy introducsd from the Coal Mining has been used ior predicting and monitoring coal burst successiully. By this way, the tunnel was excavated safely.
