通过对黑龙江省莫霍面深度起伏特征划分,将黑龙江省地壳深部构造划分为五个区,进一步分为三大构造分区.根据莫霍面深度确定三大构造分区的地温梯度,根据地层厚度和地温梯度确定煤类.对白垩系、古近系、新近系煤深成变质条件进行了分析,并对黑龙江省煤类分布进行了划分.

@@@@By the division of the fluctuating characteristics of Mohorovicic discontinuity in Heilongjiang province , we got five areas data of the crustal structure in Heilongjiang , and the geothermal gradient of the three major tectonic divisions is judged from Mohorovicic discontinuity .The types of coal is decided according to the geothermal gradient and the thickness of strata.Cretaceous, Paleogene, Neogene deep burial metamorphism of coal are analyzed in this paper as well as the division of the coal types.
