Application of High Strength and High Pretension Anchor Network Support Technology in Deep Mine Roadway Along Gob

In view of the problems of large pressure in the deep mining roadway in the deep mining area of Wanglou Coal Mine, such as serious roadway deformation and difficulties in support, this paper analyzes the characteristics of the roof and floor of the 27304 working face in the seven mining area and the lithological characteristics of the coal seam and the stress environment of the coal seam. The supporting status of the mine combined with theoretical analysis and numerical simulation, the design ideas of high strength and high pretension anchor mesh support is proposed and applied it in the roadway under 27304 working face. The field test results show that this scheme achieves the long-term stability of roadway support along deep excavation roadways in deep mines.
