Analysis of Construction Scheme of Dynamic Pressure Roadway Support in Coal Mine Working Face
In order to further explore the key points of the support scheme of dynamic pressure roadway in coal mine working face,the main problems existing in the existing support scheme of dynamic pressure roadway in a working face of H Coal Mine were taken as the research object.Firstly,combining with practical problems,simulation analysis method was applied to optimize the width of coal pillar reserved in roadway.Secondly,technical parameters of anchor cable and bolt in the support scheme were determined based on theoretical calculation method to complete the optimal design of roadway support scheme.From the actual operation effect,the optimized roadway support scheme can effectively solve the problem of surrounding rock deformation and is of certain application value.
