| Abstract: | Taking the return air roadway of Longfeng Coal Industry as the background,by analyzing the layout of return air roadway,combining with the properties of the surrounding rock in the floor,according to the different specifications and conditions of the roadway at the intersection of the openings,the opening technology of the roadway and the surrounding rock support parameters under different geological conditions are determined.The observation of mine pressure shows that the state of surrounding rock is stable and the deformation is controllable after the reasonable support parameters are adopted. |
