The utility model belongs to the technical field of geological exploration, and particularly relates to a development and utilization system for geothermal resources in a multilayer goaf. The system comprises an upper-group coal goaf, a first filtering system, a water source heat pump cooling system, a solar heating system, a second filtering system and a lower-group coal goaf, the first filtering system is connected with the upper coal goaf through a pipeline, the first filtering system is connected with the water source heat pump cooling system through a pipeline, and the water source heat pump cooling system is connected with a refrigerating system in a building and achieves heat exchange. A water outlet of the water source heat pump system is communicated with the lower coal goaf through a pipeline after passing through the second filtering system; the second filtering system is connected with the lower coal goaf through a pipeline, the second filtering system is connected with the solar heating system th
