Zusammenfassung:	The embodiment of the invention provides a dangerous rock mass composite protection structure and relates to the field of dangerous rock mass protection. The dangerous rock mass composite protection structure comprises a rock mass assembly and a protection net assembly. After a steel wire rope on the winch part is tightened and a first steel rope is stressed and tensioned, a second rope buckle at a second lantern ring is gradually unfastened till the second rope buckle relieves pressing of the first steel rope, then the steel wire rope on the winch part is tightened to drive the first steel rope to be tightened, meanwhile, after the tensioning force of the first steel rope is gradually increased and the first steel rope drives the protective net to be tensioned, the second rope buckle is screwed, a purpose of tensioning the tensioning steel rope with the smaller tensioning force is achieved, in the process, the first steel rope is in the tensioning state, the situation that all the tensioning force of the ten
