Abstract: Aiming at the limitation of conventional analysis methods in the study of mining rights layout, such as statistical analysis and manual interpretation, this paper presents a grid analysis method based on ArcGIS, which has been used in the study of the changes of mining rights layout in the Daye-Yangxin equipped exploration districts. According to the analysis results，part of prospecting rights in the prospective area of mineral deposits did not improve exploration phase, and the others reduced exploration area. Compared with the conventional methods, the grid analysis method is able to turn the irregular data into orderly data, such as the prospecting rights data. At the same time, the new method can achieve the automatic correlation of data and compare the data extracted from the minning rights database in different periods. Critical information could be more readily represented on the grid diagram. This can greatly enhance the work efficiency.
