Linear Structure information extracted from TM image were studied by quantitative analysis of the relation of their spetial distribution features and uranium mine concentration based on fractal theory and RS in the paper.It explained the mechanism of linear structure on TM Image and interpreted fault structures in brief.The results show that the fault structures in Xiazhuang Ore Field have self-similarity statistically and their distributional regularity is within scale range of 0.3125—5km and all correction coefficients exceed 0.98.It can be regarded as two fractal relation and the fractal dimension within scale range of 0.3125—1km is D1=1.0693

within scale range 1.25—1km is D2=1.7469.Farther

It shows that fault structures have multi-fractal character in the Xiazhuang Orefield.It indicates that the region has farther perspective to explore where the structures within 0.3125—1km with minor value of fractal dimension.
