摘要
本文采用X射线分析方法，研究了南票煤田热变煤中粘土矿物的变化特征，由此得出该处岩石浆侵入时对煤层的影响范围和天然焦的形成温度。
Based on the analysis of the clay mineral variations in Nanpiao thermometa morphic coal with X-ray diffraction, the extent of intrusive rocks influence on coalbeds can be delimited and the native coke forming temperature can be defined.
