The invention relates to a miniature full cross section drill hole arrangement device for model test and application thereof. The device comprises a track mechanism, a drill hole mechanism and a controller, the drill hole mechanism is arranged on the track mechanism and moves along the track mechanism, the drill hole mechanism comprises a annular track part, a radial track part, a drill part and asupporting part, the two ends of the radial track part are located on the annular track part and rotates along the annular track part in a circumferential direction, the drill part is arranged on theradial track part and moves along the radial track part in a straight line, the supporting part is located on the outer side of the annular track part and used for fixing the whole drill hole mechanism, and the controller is respectively connected with the annular track part, the radial track part, the drill part and the supporting part. According to the drill hole arrangement device, the structure design is scientific and reasonable, the degree of automation is high, the problem that by a traditional mode, drilling in the full cross section of a model experimental tunnel is difficult is solved, the precision and the efficiency of drilling are high, the coverage of the full cross section of the model experiment and drilling at any position by the drill hole mechanism can be achieved, thedevice is suitable for experimental models with various specifications.
