Lunar water ice in-situ heating mining method

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.
