Abstract. The purpose of the article is to establish the dependence of the area of regolith extraction using a screw conveyor and the possible extraction volumes on the parameters of the electric motor used, taking into account the parameters of the screw conveyor, the characteristics of the deposit, and the properties of the regolith. To achieve this goal, we used already known dependencies for calculating the parameters of the screw conveyor and the fundamental laws of loose media mechanics, the basic equations of electrodynamics of asynchronous motors, as well as the peculiarities of the behavior of loose media when moved by a screw, which were experimentally studied by domestic authors. It was possible to investigate the influence of such parameters of an asynchronous squirrel-cage motor as critical slip, maximum possible torque, and permissible value of electric motor power on the permissible limits of screw length change, extraction area, and regolith extraction volume. The permissible values of the transport distance from the diameter of the screw conveyor and its other geometric parameters, as well as the degree of screw filling, which are possible with the selected electric motor parameters, were determined. It has been established that the area of the regolith extraction site and the volume of its extraction, within the range of variation of the main parameters studied, depend almost linearly on the relative permissible power of the electric motor, and the coefficients of this dependence are determined by the critical slip value. At the same time, for all values of critical slip, the graphs of functions corresponding to larger values of this parameter are located above the graphs corresponding to smaller values. The dependencies proposed for calculating the area of the regolith extraction site and the probable volume of its extraction when using a screw conveyor driven by an asynchronous squirrel-cage motor, from the parameters of the electric motor, the geometric dimensions of the screw, the characteristics of the deposit, and the properties of the regolith, allow the design of technological schemes for the extraction of minerals on the planets of the Solar system and the determination of their permissible and optimal parameters.
Keywords: Moon, regolith, screw, electric motor, extraction area, extraction volume.
