The invention discloses a caving zone filling method based on solid-liquid-gas three-waste synergistic mineralization, and relates to the technical field of mine filling. Comprising the following steps that goaf grouting filling parameters are determined through a multi-source data fusion analysis method; the filling material is prepared by taking mining area solid wastes, mining area liquid wastes and gas wastes as basic materials; filling materials are injected into the residual space of the caving zone of the goaf of the underground working face through a ground grouting filling system, the loose gangue structure in the goaf is cemented, and a filling body is formed; the method realizes the utilization of solid-liquid-gas three wastes in the mine, achieves the purposes of reducing ground surface settlement, protecting water resources and the like, and accords with the low-carbon and high-efficiency mineral development concept. 本发明公开了一种基于固液气三废协同矿化的垮落带充填方法，涉及矿山充填技术领域；包括以下步骤：通过多源数据融合分析方法确定采空区注浆充填参数；以矿区固体废弃物、矿
