| 摘 要： | 通过对勘查区地质资料和煤质化验成果分析,阐述了煤质基本特征,初步分析认为本区的煤层由浅入深随着煤层埋深增加,变质程度也逐步增大的希尔特定律。煤类变化规律是:在地质剖面上呈现垂直分带现象,上部煤层较下部煤层变质程度低;在水平分带上,同一煤层中北部较南部变质程度高。从煤类分带图上可以看出,本区主要煤类有长焰煤(41CY、42CY)、不粘煤(31BN)、气煤(43QM、44QM、45QM)。

| Abstract: | The geological exploration and coal quality data analysis of laboratory results to the basic characteristics of coal,and draws a conclusion that this area follows the Hilt's law that with shallow to deep coal seam depth increases,gradually increase the degree of deterioration of Hilt's law.Variation of coal is phenomenon of vertical zoning on the geological cross-section,the upper coal seam is less metamorphic than the lower;in the horizontal belt,compared with the same coal seam the north is more metamorph... |
