Device for prediction underground dynamic behavior of mines by using acoustic emission sensor

Stability of the mine detection device using the AE sensor with respect to the present invention includes a housing formed to be able to be inserted into a bore hole drilling in the ground; A plurality of sensor units are arranged in the horizontal direction in the housing so formed can detect AE, respectively; And according to the dynamic behavior of the interior of the ground so that the external force to the plurality of sensor units act independently and may include a constraining member formed makes it possible to constrain the plurality of sensor units.
