摘要
Abstract
In order to solve the problem of surrounding rock control in No.9+10 coal roadway of Jingu Coal Mine,the strength relationship between roof,floor and solid coal side was established by coupling support scheme and support parameters under digital twin system.Using numerical simulation method,finite element analysis(FEA)and discrete element method(DEM),FLAC3 D model was established to simulate the support effect of different row spacing of hard roof in No.9+10 coal roadway of Jingu Coal Mine,and determine the support scheme of roof with different row spacing.Through the observation of roadway surface displacement and roof drilling peep,the support effect was good.关键词
