不同成因类型煤的可选性评价

Evaluation on coal washability of different genetic coal seams

    摘要
  • 摘要: 煤的可选性受控于煤的聚积环境。通过对内蒙古乌达矿区主采煤层9、10、12、13和15煤中黄铁矿和粘土矿物的赋存特征与煤层成因关系的研究,发现河控下三角洲平原形成的煤层中黄铁矿含量低,粘土矿物含量高,其可选性较好;潮控下三角洲平原形成的煤层,其硫分含量高,粘土矿物含量较低,其可选性中等,而在潮坪沉积基础上形成的煤层中黄铁矿和粘土矿物的可选性最差。

     

    Abstract: The coal washability is controlled by coal accumulating area.The research on relationship between characteristics of pyrite and clay mineral distribution and the coal genesis types of main minable coal seams No.9, No.10, No.12, No.13,and No.15,in the Wuda mining area,Inner Mongolia,indicated that the coal seams formed in a fluvial-dominated delta plain are characterized by low pyrite content,high clay mineral content and better washability,but the coal seams formed in tide-dominated delta plain are characterized by high sulfur,low clay mineral content and the mid degree of washability.In addition,the washability of pyrite and clay mineral of the coal seam formed in tidal flat is the worst.
