Temperature determination method for lunar helium-3 resource in-situ exploitation heat release

Abstract

The invention provides a lunar helium-3 resource in-situ exploitation heat release temperature determination method, and belongs to the technical field of lunar resource exploitation. The method comprises the following steps: selecting ilmenite as a representative mineral of lunar helium-3 resource occurrence, carrying out numerical solution by utilizing an established physical model of lunar mineral occurrence helium-3 resource, and establishing high-vacuum and low-gravity physical conditions to conform to the actual environment of the moon; analyzing the evolution law of the release amount and the release rate of the helium-3 resource in the ilmenite along with the heating temperature and the heating time, and finally, comprehensively considering the release rate and the release amount of the helium-3 resource in the lunar soil to determine the optimal heating temperature for in-situ mining of the lunar helium-3 resource. According to the method, the energy consumption ratio during in-situ mining of lunar helium-3 resources can be reduced.

Description

technical field [0001] The invention relates to the technical field of lunar resource mining, in particular to a method for determining the temperature of the heat release in the in-situ mining of lunar helium-3 resources. Background technique [0002] Due to the environment characteristics of high vacuum and low gravity on the moon, the solar wind can be directly injected into the lunar soil, so that a large amount of solar wind materials are stored in the lunar soil, including helium-3 materials. Helium-3 is an efficient, clean, and safe controllable nuclear fusion fuel. 10 tons of helium-3 can meet all the energy needs of the country for a year. At the same time, there are no neutrons in the thermonuclear reactor of helium-3. 3 When used as an energy source, it will not produce radiation. In-situ mining and utilization of helium-3 resources on the moon has become the research content of many countries, which can not only reduce the cost of deep space exploration missions...
