摘要
Abstract
To solve the difficulty of supporting the stoping roadway in the 8303 working face,a comprehensive study is conducted on the mechanism of large deformation of the roadway surrounding rock through methods such as testing the physical and mechanical properties of coal seams,testing ground stress,and analyzing the lithology of the roof.By conducting a loose circle test,a reasonable form of roadway support is inferred,and a segmented shed support technology for the entire roadway is proposed.Measure the displacement amount of surrounding rock during the roadway excavation period of the working face.The experimental results show that the relative displacement amount of the roof and floor is reduced by 69%-77%compared to the original roadway support scheme;The displacement amount of the two sides is reduced by 80%-88%compared to the original roadway support scheme.Adding full roadway shed support technology to the original roadway support system can effectively weaken the influence of composite roof on the roadway,and the effect of controlling the surrounding rock deformation is relatively significant.关键词
