Compared with the conventional resistivity method, the electrode of the high-density electrical method can be completed at one time during the field arrangement, which not only reduces the fault and interference caused by the electrode setting, but also greatly improves the efficiency of the electrical method exploration. In addition, a variety of electrode arrangements can be selected for measurement using high-density electrical exploration, which can help explorers to obtain more abundant information of geoelectric section. Third, high-density electrical exploration also achieves the goal of automatic or semi-automatic field data acquisition, which effectively helps explorers to collect data quickly and effectively avoids hidden dangers caused by manual misoperation.
