A method for in-situ heating and mining of lunar water ice

Abstract

The invention provides a method for in-situ heating and mining of lunar water ice, which belongs to the technical field of lunar resource and energy mining. This method first extracts the physical parameters of the water-bearing lunar soil in the target mining area, and then uses the in-situ collection model of the water vapor capture cover to calculate the pressure of water vapor in the capture cover and the water ice collection rate under different heat conduction rod temperatures during stable production. According to the obtained water vapor pressure in the trapping hood under different heat conduction rod temperatures, the optimal mining temperature of water ice is determined. Based on the extracted physical parameters, the temperature of lunar soil during the thermal mining of water ice is numerically solved. Finally, according to the obtained The optimal mining temperature of water ice and the spatio-temporal distribution of lunar soil temperature under different numbers of heat conducting rods were used to calculate the optimal number of heat conducting rods for water ice mining for a given maximum heating time. The invention realizes the optimization of the mining scheme of water ice in the polar region of the moon, and lays a foundation for realizing the in-situ utilization of lunar resources in the future.
