The umber hulk can burrow through solid rock at half its burrowing speed and leaves a 5 foot-wide, 8-foot-high tunnel in its wake. Others, like the Ankheg and your exemplary Blue Dragon, also leave tunnels behind them. However, it depends on the environment whether the tunnels remain, or immediately collapse.

What is a burrow speed?
But the general question does have an answer: burrow speed is defined in the Monster Manual, on p. 8, and only allows you to move through sand, earth, mud, and ice (not creatures or rock, including marble): A monster that has a burrowing speed can use that speed to move through sand, earth, mud, or ice.
What can a monster do with its burrowing speed?
A monster that has a burrowing speed can use that speed to move through sand, earth, mud, or ice. A monster can’t burrow through solid rock unless it has a special trait that allows it to do so. I could imagine that whether or not you can create a tunnel behind you depends on the medium you are digging through.
Can a burrow monster glide through the Earth?

Can a worm burrow through rock at half its speed?
The worm can burrow through solid rock at half its burrow speed and leaves a 10-foot-diameter tunnel in its wake. Now just because one monster has an attribute doesn’t mean another does/does not have a similar feature. But it does suggest that digging through rock or something else may NOT leave a tunnel, otherwise why would they say that?
What do burrowing animals do in the ground?
