Pressure relief hole construction method based on dynamic monitoring of mining stress

The invention provides a pressure relief hole construction method based on dynamic monitoring of mining stress, and relates to the technical field of mine impact ground pressure prevention and control. In particular, a measuring drilling hole is drilled in a first mining face transportation cis-groove of a mining area, a mining stress distribution curve of the mining face is obtained by measuringa drilling hole A, and a vibration frequency map is obtained by measuring a drilling hole B; after the first mining face is mined, holes are drilled into one side of the mining face in an empty roadway at the next mining face, and the mining stress distribution of a drilling hole C and the vibration frequency map of a drilling hole D are obtained correspondingly; and the relation between the mining stress distribution and the vibration frequency of a drill rod is obtained by comparing the stress distribution curve of the drilling hole A and the drilling hole C with the vibration frequency mapof the measurement drillin
