摘　　要：通过对煤的变质成因分析,认为宝鼎煤田煤类多样,分布格局独特的原因是煤层在广泛深成变质作用基础上,局部叠加了岩浆热变质作用的结果。根据研究结果探讨了宝鼎煤田煤变质模式,预测了深部的煤质变化,指出F22断层以西为下一步JM的有利寻找方向。Extensive plutonic metamorphism superimposed partly by magmatic metamorphism resulted in diverse coal types and unique coal distribution patterns in the Baoding coal field. A coal metamorphism model for the Baoding coal field is discussed. The variation in coal quality in the depth is predicted with the range of reconnaissance to the west of F22.
