摘　　要：通过对研究区内勘探工作取得的大量基础性资料进行整理分析,发现研究区上二叠统含煤岩系从西到东,煤层总厚、含煤层数、可采总厚、可采层数均有逐渐减少的特点,其中左鸠戛-鸡场一带为富煤带;因受垭都-紫云大断裂带影响,富煤带以长条状的形态呈现,且方向与垭都-紫云大断裂带方向保持一致;此外,从古植物、古气候、古地理、古构造四大方面论证了左鸠戛-鸡场富煤带的形成。Through reviewing the amount of basic data acquired by exploration in Zhina mining area,the total thickness of coal seams,the coal bearing numbers, the total minable thickness and the total mining layers of coal bearing series on the upper Permian all decrease gradually from west to east. The area is coal-rich zone from Zuojiujia to Jichang. The coal-rich zone presents in a strip shape owing to the fault of Yadu-Ziyun and has the same direction with the fault. Besides, the formation of the coal-rich zone from Zuojiujia to Jichang is proved by ancient plant, climate, geography and structure.
