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 a great deal of basic information obtained from the exploration work in the study area, it is found that the Upper Permian coal-bearing rock series from west to east, the total thickness of coal seam, the coal seam number, the total recoverable thickness, the recoverable layer number Which are gradually reduced. Among them, Zuojiaohuan-Zhuchang area is rich in coal belt; due to the influence of the Yudu-Ziyun great fault zone, the coal-rich zone presents in the shape of a long strip with the direction of Yudou-Ziyu In addition, the formation of rich coal belt in Zuojuta-Jichang has been demonstrated from the four aspects of ancient plants, ancient climate, paleogeography and paleostructure.
