摘要
In this paper, it try to do tentative study of vortex structure stress intensity, coal-forming mineralization intensity and the semi-quantitative relation with the center distance from deposit to knob. The results shows that the coal deposits in western Guizhou and eastern Yunnan provinces are controlled by Fa’er off-cutting turbine shape structure, this is an important coal control model, its coal-forming mineralization intensity is controlled by structural stress field, the high mineralization intensity position is in the center turbine shaped structural stress field, the coal-forming mineralization intensity and the distance form deposit to center knob are appeared as some nonlinear functions of normal distribution.
