| Abstract: |
| Choose the position of the Crustal Stress measuring point according to lithology, use method of stress relief by overcoring to test the three-dimensional geo-stress, and get the result that the maximum principal stress has a linear growth with the increase of the depth by linear regression, which can make the crustal stress better used to predict the rock burst. Describe the probability of rock burst from the mechanical demand, brittle, integrity, and energy storage requirements four aspects, increase the accuracy of rock burst tendentiousness prediction, and it is consistent with the field position of rock burst. |
