摘要
Abstract
Aiming at the stability problem of high stress full section coal roadway,taking the 5108 working face transportation roadway of Laomupo Coal Mine as the research background,the failure characteristics of the roadway under the situation of original support parameters of the 5108 working face transportation roadway are analyzed.Using FLAC3D numerical simulation software,different support parameter gradients are set to analyze the impact of support parameters on surrounding rock deformation,the optimized support parameters are determined,thus,the 3D collaborative support control technology is provided to achieve the purpose of reasonable control of changes in the roadway surrounding rock.The research results indicate that using the optimized support scheme,the maximum deformation amount of the roof is less than 210 mm,and the maximum convergence amount of the two sides is less than 300 mm.关键词
