| Abstract: | This paper investigates the structure and mechanism of rockbolt installed at the periphery of roadways for forepoling by simulation test. The test results have shown that this method is capable to support broken rocks which are liable to collapse with small supporting force. The mechanical model and the design principle for the structure are presented in this paper. |

| Keywords: | forepoling bolt underground pressure surrounding rock. |
