Embodiment 1

[0042] Such as figure 1 As shown, a thermal mine development system provided in this embodiment includes a large-diameter vertical shaft 2, which can be constructed through vertical shaft construction technology, or a blind shaft can be built by using the existing shaft in mining. The diameter of the large-diameter shaft 2 is 3-10m, and its vertical depth is 3000-10000m, until the underground is opened up to form an underground high-temperature and high-pressure heat exchange pool 3, which has a diameter of 30-50m and a height of about 1m. It is related to the number of layers provided in the heat exchange guide channel 4 . Both the injection pipeline 8 and the collection pipeline 9 are arranged along the inner wall of the large-diameter shaft 2, and form a heat exchange and flow guide channel 4 in the underground high-temperature and high-pressure heat exchange pool 3. The injection pipeline 8 and the collection pipeline 9 are made of high-temperature, high-pressure and heat-...

Embodiment 2

[0058] Such as figure 2 As shown, a thermal mine development system in this embodiment includes a large-diameter vertical shaft 2, and the shaft can be constructed through shaft construction technology, or a blind shaft can be constructed by using an existing shaft in mining. The diameter of the large-diameter shaft 2 is 3-10m, and its vertical depth is 3000-10000m. The underground high temperature and high pressure heat exchange pool 3 is formed by underground development. The diameter of the underground high temperature and high pressure heat exchange pool 3 is 30-50m, and the height is about 1m, which is related to the number of layers of the heat exchange and flow guide channel 4. Both the injection pipeline 8 and the collection pipeline 9 are arranged along the inner wall of the large-diameter shaft 2, and the injection pipeline 8 and the collection pipeline 9 are made of materials resistant to high temperature, high pressure and heat insulation.

Abstract

The invention discloses a loose blasting type hot ore development system and a construction method thereof. The hot ore development system comprises a ground lifting system, a large-diameter verticalshaft, an underground high-temperature high-pressure heat exchange water tank, a heat exchange flow guide channel, a water-rock geothermal flow storage layer, a movable sealing device and the like, wherein the water-rock geothermal flow storage layer is formed by access blasting tunnels and a main tunnel. The hot ore development system is provided with an injection pipeline and a collecting pipeline along the inner wall of the large-diameter vertical shaft, the injection pipeline communicates with the collecting pipeline through the heat exchange flow guide channel of the underground high-temperature high-pressure heat exchange water tank in dry hot rock, the circulating main tunnel is arranged around the underground high-temperature high-pressure heat exchange water tank, and the plurality of rows of access blasting tunnels are horizontally arranged along the main tunnel, a hot ore blasting fracture flow storage layer is formed through caving mining method loose blasting, moreover, the movable sealing device is arranged above the vertical shaft of a blasting layer, through a U-shaped pipe principle, through the injection pipeline and the collecting pipeline, cold water and hot water in the high-temperature high-pressure water tank exchange heat energy, the water with the heat energy is conveyed to the ground to be converted into electric energy for people to use, and dual heat exchange is realized.

Description

technical field [0001] The invention belongs to the technical field of geothermal development, and in particular relates to a thermal ore development system and a construction method thereof. Background technique [0002] As the world's energy supply and demand are becoming increasingly tense, and traditional energy is facing shortages and high carbon emissions, the development and utilization of new energy has become a research and development hotspot, among which the research and development of 3000-10000 meters deep geothermal energy resources is getting more and more people's attention However, due to the limitations of drilling technology, the utilization rate of geothermal resources is not high. Geothermal heat mainly comes from radioactive decay inside the earth, and the heat source is sustainable on a scale of hundreds of millions of years. Deep geothermal development is the fundamental way to solve the future energy problems of mankind. [0003] Using geothermal en...
