| Abstract: | Simulating test with space similarity material, this paper studies the rules of deformation and instability of surrounding rock when sinking a shaft with mixed working method at four, eight meter segment. The authors get the distribution and development rules of radial displacement of surrounding rock, and also get the form and place of surrounding rock instability, though analysis of the test result. At last, the paper suggests increasing the current segment in our country. |
