Summary:The utility model provides a geothermal utilization system for a coal mine underground space, which is characterized in that a coal mine underground space reservoir is arranged in the coal mine underground space, and a circumferential side water-resisting layer and a lower end water-resisting layer are arranged in the coal mine underground space; a side and bottom water-proof space formed by mutually connecting the peripheral side water-proof layer and the lower end water-proof layer is a coal mine underground space reservoir; geothermal water of a coal mine underground space reservoir is conveyed to the ground through a heat extraction well and conveyed to heat exchange equipment through a ground geothermal water conveying pipeline I, and after heat exchange and extraction, geothermal tail water obtained after heat extraction is conveyed to a recharge well through a ground geothermal water conveying pipeline II; then the geothermal tail water is recharged into the coal mine underground space reservoir throug
