Abstract：Aiming at lacking dedicated control technique of complex rockbursts in coal mines,the authors propose a 7-component framework for controlling rockbursts based on rockburst classification,the 7-component framework includes classification,evaluation,danger-breaking,early-warning,inspection,support and management.Through analyzing mining depth,overburden,coal seam,tectonics,mining method and boundary conditions,the eight external load types and ten typical surrounding rock structures of under-ground openings are identified.Subsequently,a comprehensive rockburst classification scheme is presented using different combinations of external loads and surrounding rock structures.The evaluation,dan-ger-breaking,early-warning,inspection,support and management technology are analyzed and optimized based on rockburst classification.The 7-component rockburst control framework has been successfully applied in Xinjulong Coal Mine of Shandong Energy Group,and ensured the deep mining safety.
