新疆哈尔交矿区海陆交互相赋煤特征分析

Analysis on Coal-bearing Characteristics of Marine-terrestrial Interactive in Xinjiang Haerjiao Mining Area

哈尔交煤矿区是新疆少有的二叠系成煤的典型矿床,通过对其成矿地质背景、含煤岩系、构造特征、煤层特征、煤质特征和成煤条件研究,表明煤层发育于二叠系卡拉岗组火山活动间的相对宁静期的第三岩性段海陆交互河湖相,煤层夹于凝灰岩中,煤化程度高,资源禀赋良好,可作为民用煤或合成氨的原料等。

Haerjiao coal mining area is a rare typical Permian coal-forming deposit in Xinjiang.Through the study of its ore-forming geological setting,coal-bearing rock series,structural characteristics,coal seam characteristics,coal quality characteristics and coal-forming conditions,it is shown that the coal seam is developed in the marine-terrestrial interactive fluvial and lacustrine facies in the third lithologic section of the relative quiet period of the Permian Karagang formation,and the coal seam is sandwiched in the tuff with high degree of coalification and good resource endowment.It can be used as raw material for civil coal or synthetic ammonia,etc.
