There is no single answer. Depends what type of mine (coal or metalliferous), size and design of blast, precautions taken... etc.
It is possible to safely blast within 100m of houses... in which case you could be that close.
However a poorly setup blast can throw rock more than a km...
Can you be a bit more specific with the question?
