The raiders heard about your vault, but never accessed it from the tunnels. It's an unfinished tunnel, and there's nothing to do down there. Although you can't get to a vault from those tunnels, there is a mission later in the game that will allow you back into Vault 101.
I think that they were trying to dig into your Vault. So there isn't a Vault underneath the school. If you go to the Vault corporate building, you can download all the Vault locations to your PIP boy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
