| 摘 要： | 本文试图对旋卷构造应力强度与成煤矿化强度、成煤矿化强度与矿床至旋扭中心距离(r)的半定量关系,作一尝试性研究。结果表明,发耳偏心涡轮状构造控制着贵州省西部——云南省东部若干煤田的分布,是一种重要的控煤构造型式,其成煤矿化强度受构造应力场控制,其矿化强度高值区位处涡轮状构造应力中区,而成煤矿化强度与矿床至旋扭中心的距离(r)呈现一种类似正态分布的非线性函数关系。

| Abstract: | 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 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. |
| |
| Keywords: | structural stress intensity coal-forming mineralization intensity normal distribution function |
