Abstract In gobi region of Xinjiang, annual rainfall is rare, water evaporation is strong, surface is dry, and hence it is easy to form a thin layer of dry Quaternary matter accumulation. High-power induced polarization geophysical prospecting requires a higher current, and electrode grounding resistance is often buried in a dry surface and is often quite large, which causes great difficulty in power supply. To effectively solve this problem and achieve the feasibility of high-power IP exploration, the authors took into account the increase of production efficiency, consulted the results of previous studies as well as production experience and, on such a basis, summed up and implemented a method for improving grounding resistivity in the dry thin-layer loose surface area, i.e., the use of wet soil buried porous sheet electrodes. The application of this method not only solves the problem of electrode power supply in such a region but also improves the efficiency of production. In addition, field exploration data quality is significantly improved and good effects can be achieved.
