What kind of support are you using? Tiles are only supported if the center coordinate is within the radius of the support. The visual guide in game is useful, but not exact. RoB wiki shows visuals of each support with the "safe" tiles marked. (Note: "Mine Beam" does not have this, but not many people use them regularly due to the cost. The stone column is most popular due to the amount of trash stone dug out of any given day mining.) Also note that Tower caps have a slightly smaller radius than the base mining support, which throws the safe area off significantly.
Also, pay attention to the cave dust. While it's fastest to just mine it all, it's safest to make sure to avoid the "damage" tiles and only mine out the "0 spaces." I quit blowing it all out when I got tired of forgetting to keep an eye on the nearby supports and broke a few that way.
If you continue having problems, a screenshot of the area could help demonstrate what's going on.
