The invention provides a method for detecting and repairing a mine distributed type underground reservoir, which comprises the following steps of: surveying the mine distributed type underground reservoir; analyzing the position with the hidden danger of the underground reservoir according to the survey result; and repairing the position with the hidden danger. The method can be used for surveying the underground reservoir before or when the underground reservoir is in use, the position with the potential safety hazard can be found out in time by surveying the underground reservoir, and the position with the hidden danger can be plugged by grouting, so that the accidents caused by the instability of the structure of the underground reservoir can be avoided, the stable running of the underground reservoir can be realized, and a scientific and reasonable method is provided for protecting the safe running of the underground reservoir.
