The invention relates to the technical field of industrial solid waste treatment, in particular to a composition for preparing a filling material, a preparation method of the filling material and a method for filling a mine. The composition for preparing the filling material comprises aggregate, a cementing material and an additive, the aggregate comprises coal gangue; the cementing material comprises cement, gasified slag and fly ash; the additives comprise a first additive and a second additive; the first additive comprises a polycarboxylate superplasticizer; the second additive comprises any one of a calcium lignosulphonate water reducing agent, dispersible latex powder and an organic early strength agent. The coal gangue is used as aggregate of the filling material, the cement is used as a chemical activator to improve the cementing property of the fly ash and the gasified slag, and the first admixture and the second admixture synergistically improve the pump injection effect of the filling material during pump injection and improve the compressive strength of the filling material after curing.
本申请涉及工业固废处理技术领域，具体而言，涉及一种用于制备充填材料的组合物、充填材料的制备方法以及充填矿井的方法。用于制备充填材料的组合物包括集料、胶凝材料以及外加剂；集料包括煤矸石；胶凝材料包括水泥、气化渣以及粉煤灰；外加剂包括第一外加剂以及第二外加剂；第一外加剂包括聚羧酸减水剂；第二外加剂包括木质素磺酸钙减水剂、可分散乳胶粉以及有机早强剂中的任意一种。煤矸石作为充填材料的骨料，水泥作为化学激发剂以提高粉煤灰和气化渣的胶结性能，第一外加剂和第二外加剂协同提高充填材料在泵注时的泵注效果以及提高充填材料在固化后的抗压强度。
