The invention discloses a cavity material made of mine tailing, and relates to the technical field of cavities. The cavity material is prepared from, by weight, 50-55% of tailing, 15-20% of quicklime,5-10% of cement, 1-5% of phosphogypsum, 1-3% of nano-diamond powder, 5-10% of zirconium silicate, 60-65% of water and 0.1-0.3% of additives; the cavity adopts the mine tailing as the main ingredient,the accumulated mine tailing is comprehensively utilized, the pollution problem caused by accumulation of the tailing on the environment is solved, and meanwhile full utilization of the mine tailingis achieved, the dosage of cement is lowered, the production cost is reduced, and the energy conservation and environmental protection effects are significant, and the obvious economical efficiency isachieved; by means of the nano-diamond powder added in the cavity material, the wear resistance and fracture resistance of nano-diamond can be utilized, the wear resistance, hardness and fracture toughness of the cavity are eff
