Embodiment Construction

[0038] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0039] The invention provides a method for in-situ heating and mining of lunar water ice.

[0040] Such as figure 1 As shown, the 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 pressure at different temperatures of the heat conducting rods during stable production. Collection rate, according to the obtained water vapor pressure in the trapping hood under different heat conduction rod temperatures, determine the optimal mining temperature of water ice, based on the extracted physical parameters, numerically solve the temperature of lunar soil du...

Abstract

The invention provides a lunar water ice in-situ heating mining method, and belongs to the technical field of lunar resource and energy mining. The method comprises the following steps: firstly, extracting physical property parameters of water-containing icy lunar soil in a target mining area, then calculating the pressure intensity of water vapor in a trapping cover and the water-ice collection rate at different heat-conducting rod temperatures during stable production by utilizing a water vapor trapping cover in-situ collection model, determining the optimal mining temperature of water ice, carrying out numerical solution on the temperature of lunar soil in the water ice thermal mining process based on the extracted physical property parameters, and finally calculating the optimal number of heat-conducting rods for water ice mining within the given maximum temperature rise time according to the obtained optimal mining temperature of water ice and spatial and temporal distribution of the temperature of lunar soil under different numbers of heat-conducting rods. According to the method, the water ice mining scheme of the lunar polar region is optimized, and a foundation is laid for in-situ utilization of lunar resources in the future.

Description

technical field [0001] The invention belongs to the field of lunar resources and energy mining, and relates to a method for in-situ heating and mining of lunar water ice, in particular to a method for realizing efficient in-situ mining of lunar water ice by constructing and optimizing a lunar water ice mining system with an in-situ thermal mining method method. Background technique [0002] As the closest celestial body to the earth, the moon has become the first choice for human extraterrestrial celestial body exploration and resource utilization due to its unique spatial location and broad scientific exploration prospects. Among them, the establishment of a lunar base is a key step. Realizing the in-situ utilization of lunar water resources is of great significance for the establishment and lasting operation of future lunar bases. For example, in situ harvested water ice can be processed to directly provide the drinking water needed to sustain humans in lunar bases. At ...
