Abstract

The invention discloses a mine geothermal exploitation and utilization device with solid-flow coupled collaborative cooling, including a mine geothermal exploitation and utilization device and a stope air treatment and transportation device. A hot filling body, a U-shaped heat exchange coil vertically laid in the heating filling body, a sub-collection system arranged on the ground, and a water supply and return system for connecting the sub-collection system and the U-shaped heat exchange coil; The stope layer air treatment and transportation device includes a ground cold water treatment device, an air treatment unit and an air supply pipe for feeding fresh air into the mining space of the mine; the invention also discloses a mine geothermal mining with solid-fluid coupling collaborative cooling Utilize method. Through the solid-flow coupling synergistic cooling effect, the invention can achieve a good stope cooling effect and create a comfortable underground thermal environment; the value of the underground heat exchange system is improved, the practicability is strong, and the popularization and application value is high.

Description

technical field [0001] The invention belongs to the technical field of deep mine mining, and in particular relates to a mine geothermal mining utilization device and method with solid-fluid coupling and coordinated cooling. Background technique [0002] With social development and increasing demand for resources, shallow coal resources are gradually decreasing or even exhausted. In order to ensure resource security and expand economic and social development space, countries around the world have entered the stage of deep resource mining. However, with the increase of mine mining depth, the high temperature heat damage induced by deep ground temperature has become more and more serious, which has become an important factor restricting the safe and efficient mining of deep deposit resources. The existing statistical data show that the average mining depth in Germany is 900m, the average ground temperature is 41°C, the deepest is 1712m, and the highest ground temperature is 60°...
