| Abstract: | In order to give full play to the bearing capacity of roadway surrounding rock,taking the 1-1022 roadway as the engineering background,the feasibility of active control of roadway under hard roof is analyzed.With the idea of strengthening the soft rock layer of direct roof and making full use of the hard rock layer of basic roof,the active support of high-strength and high pretension bolt and the strengthening support of prestressed anchor cable as the core,the active control of anchor net cable beam under hard roof is developed.The surrounding rock deformation of the test roadway is effectively controlled by the technology. |
