The Kunlun coal-bearing zone can be divided into three zones: the East Kunlun coalfield, the Buerhandashan zone, and the Hongshuihe zone, from east to west, respectively. Currently, coal is only found in East Kunlun coalfield, in Tatuo coal mine, Hongtupo coal mine and Kuhai coal mine, all of which are small-sized and formed in Early or Middle Jurassic. In this paper, the authors compared the coal mine characteristics between Tatuo and Quiji coal mines and analyzed the depositional formation, distribution of coal and strata sequence and gravity anomaly of the coal-bearing strata, then discussed the coal potential in the Qiujin zone, and guide the direction of the future explorations.
