Do you mean a land mine, if so people use a combination of metal detectors, trained aminals, or by check the land carefully in front of you.
If you are talking about a mine for coal you can’t really clean it, it is a process of making it safe and understanding what going to happen to the water when it goes back into the mine. You have to make the mine save, like filling in shafts stopping up entrances to the mine. With the water we have to try and predict where and when it will reach the surface. It can take up to 25 years for the mine to fill back up to the surface. Once at the surface we have to capture it and then treat.
