Study on the Stress of Surrounding Rock in Strong Dynamic Pressure Mining Roadway of Isolated Island Working Face
In order to solve the problems of poor stability and severe rock damage in the mining roadway of isolated working faces,numerical simulation software was used to analyze the stress and deformation of the surrounding rock during the excavation and mining process of the roadway.It was found that the stress around the roadway was relatively small during the excavation process,but the stress on the left side of the roadway was large.Anchor rods and cables need to be used to reinforce and support the left side of the roadway.At the same time,the vertical and horizontal stress,displacement and deformation of the roadway during the mining process were analyzed,and the weak points of the support on both sides of the roadway were identified,providing a theoretical basis for the design of subsequent support schemes and efficient and safe mining of isolated working faces.
