In order to solve the problem that traditional support schemes cannot achieve the same support effect and overall control of surrounding rock due to the complex stress of the roadway under the goaf,taking the 3#coal seam as an example,based on the analysis of its geological conditions,the stress field distribution in the goaf was analyzed using FLAC3D software,laying the foundation for the subsequent support scheme design.Through theoretical calculations,targeted support design was carried out for the internal and external staggered sections of the mining roadway,and the support effect was verified through actual measurements.
