| Abstract: | Base on the bolt support project of the open-off cut gateway in 107 coal mining face of Huangling No.2 Mine as the engineering background,the equivalent elliptic method was applied to calculate the surround rock failure scope of the large span rectangular roadway and the support parameters of the roadway were set up.The site monitoring and measured results showed that the support result of the mine roadway was excellent and the calculation of the support parameters was correct.All above could provide a new ... |
