结合厦门翔安海底隧道应用三臂凿岩台车进行钻孔注浆施工的案例，通过多臂凿岩台车与其他钻孔设备的比较，介绍多臂凿岩台车在矿山法暗挖隧道全—强风化地层进行超前预注浆的应用技术及相应适用范围，供类似工程施工参考。

Taking the application of the 3boom rock drilling jumbos in the advance pregrouting hole drilling during the construction of Xiang'an subsea tunnel in Xiamen as an example, the author presents the application technologies and application scopes of multiboom rock drilling jumbos in advance pregrouting hole drilling in fullyheavily weathered ground during construction of mined tunnels, by making comparison and contrast between multiboom rock drilling jumbos and other drilling machines. This paper can provide reference for similar projects in the future.
