滇东北地区煤炭资源丰富，是中国西南地区重要的煤炭资源基地。以以往地质研究成果为基础，综合分析野外地质调查、山地工程、钻探等资料，对研究区内主要含煤岩系上二叠统可采煤层在空间上的变化规律进行了研究，研究发现区内可采煤层空间上自东向西，时间上自宣威早期至宣威晚期，可采煤层层位自下向上迁移，可采区域随煤层层位的抬高由东向西迁移。并分析了造成上述变化规律的原因。研究表明西高东低的古地理条件、渐趋稳定的构造条件和周期性的海平面升降共同控制了可采煤层分布与迁移规律。并指出了不同地段的可采煤层层位及可采区段，对区内煤炭资源的开发具有现实指导意义。

Northeastern Yunnan has rich resources and hence serves as a major coal resource base area in southwestern China. Based on previous researches in the study area, the authors made a comprehensive analysis of field geology, mountain projects and drilling data and, on such a basis, investigated the variation regularity of mineable coal seams in major Upper Permian coal-bearing strata. The results show that, spatially from east to west and temporally from early Xuanwei to late Xuanwei, the mineable coal seams are uplifted and tend to‘migrate’from the bottom upward. An analysis of the factors responsible for such variation regularity and the variation of the ancient geography from west to east shows that the gradually stabilized structural conditions and periodic eustatic sea level jointly control the distribution and‘migration’of the mineable coal seams. In addition, the mineable coal-seams and mineable segments in different places are pointed out, which is of practical guiding significance for the exploitation of the coal resources in the study area.
