| Abstract: | The geological characteristics of mineable coal seams in Xinda mine area was introduced in detail in this paper.According to the analysis on the testing data of core-drilling coal samples and the gas desorption data,it showed that the microlithotype of mineable coal seams was mainly vitrinerite;the coalification was in accordance with the general rule of hypozonal metamorphism;the coal body structure was mainly original structure;and the mineable coal seams are all methane-enriched coalseams. |
