That's the way I do it. It works well.
The Burial Chambers are indeed deliciously creepy with those sound effects, but that's all they are - sound effects. Other than the skeleton noises, you have zero chance of encountering whatever made those noises. Still, I hope they change that, maybe adding rock falls or some kind of mini boss. I also hope for some forthcoming upper tier pick ax that lets you break through dead ends into something even more sinister.
