Abstract: 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.There have been few exploration work done in this coal-bearing belt.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.Unlike East Kunlun coalfield,the formation age of the coal-bearing strata spread in the other two zones is later Trassic and early Jurrasic.Both of these two zones have very low exploration work because of rough terrain,including the high elevation,and limited roads.The Qiuji zone located in the middle part of Kunlun coal-bearing zone belongs to the Buerhandashan zone,where some small-sized coalpits exist.From previous coal explorations,this zone is found to have coal-bearing potential,which are divided:the early Jurrasic and middle-Jurrasic strata;of these,some parts of them can be recoverable.In this paper,we compared the coal mine characteristics between the Tatuo and the 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.
