To solve the problems of fragmentation,roof subsidence,and floor heave faced by traditional support parameters in deep channel roadway support,based on the analysis of the geological conditions and support status of the 3#coal seam mining roadway,the support parameters were optimized using the anchor coupling theory to achieve secondary coupling between the support method and the surrounding rock of the roadway.At the same time,four observation points will be arranged on site to comprehensively monitor the support effect and analyze its social benefits.
