The invention relates to a simulation device and method for multi-water-source supply of overlying thick aquifer damage in coal mining, and the simulation device comprises a box body, an aquifer supply system and a vertical pressure relief assembly. The box body is provided with a containing space, and a water-resisting layer, a water-containing layer and an overlying stratum pressurizing device located above the water-containing layer are laid in the containing space from bottom to top; the aquifer supply system is provided with a plurality of water injection devices, and the water injection devices are configured to inject water to different depth positions of an aquifer. The number of the vertical pressure relief assemblies is multiple, and the multiple vertical pressure relief assemblies are arranged below the water-resisting layer in a scattered mode and are configured to support the water-resisting layer and control pressure relief at different positions of the water-resisting layer. According to the ap
