본문내용

The best and concrete way to verify under the earth crust is to excavate the surface and get into underground however it is not feasible and practical in economic and engineering perspective. In this case, however, we can delineate inside the surface with high level of confidence by employing various geophysical surveying methods.

Among these prospecting tools, the main tool that this paper will discuss is magnetic method which is oldest, simplest, fast, most economical and suitable for initial stage of mineral surveying. As other prospecting methods, magnetic survey also has its limit of technological utilization on context of geology and mining operation. Hence, it is anticipated that we can maximize the effectiveness of magnetic survey through the comparison of geophysical tools and the analysis of its pros and cons.
