Processing Method of Geological Data in Contour Map based on Surfer

Abstract

With the development of geological science, contour maps play an increasingly important role in mineral exploration and production. At present, there are lots of software for automatically generating contour maps, among which the Surfer software launched by Golden Software of the United States is the most widely used. However, the geological contour map has its own characteristics. If it is directly processed by Surfer software without processing, it is difficult to generate a geological contour map that conforms to the actual situation. Based on the author's many years of using Surfer software, this paper takes the contour map of coal seam thickness as an example. The method of processing geological data in the contour map by using Surfer software is summarized, so that the automatically generated contour map is as close as possible to the geological reality.
