| Abstract: | The analyzed the features and difficulties of the support for goaf left by small coal mine in the mine shaft bottom of Shuguang Mine. The paper provided the support alternatives of grouting reinforcement, high strength bolting and pre-stressed bolt and anchor support. The mine strata pressure measured results showed that the support mode could meet the support requirements of the goaf left by small coal mine in mine shaft bottom of Shuguang Mine, which solved the mine roadway support under the special geological conditions. |
