Abstract
In order to figure out the complexity of Shengquan Minefield fault structure, the required sample data was reorganized and collected in accordance with the field measurement data and the geological information of the 15th coal layer of the minefield. Firstly, according to the exposure condition of the drilling hole, the rose diagram of the fault direction was drawn after specifically collecting the nature, direction, and height gap and realize the visualization of the fault field measurement data, so the complexity of sectional structure can be initially analyzed. Secondly, the similarity dimension model was built through the box-type covering method in order to count the grid number of the fault trace under each sideline, and then the result was applied to the logarithmic coordinate system. By using the least square method, the slope of the bridging curve and, moreover, the fractal dimension value were achieved. Finally, Sufer was applied to draw the contour map of the fractal dimension value. The research result indicates that, through a series of quantitative analyses, this field can be divided into a simple tectonic area, mid-complex tectonic area, and complex tectonic area.
