兴达矿区可采煤层地质特征初探

Discussion on the geological characteristics and gas-bearing properties of mineable coal seams in Xinda mine area

介绍了兴达矿区可采煤层的地质特征,分析了其钻孔煤芯化验资料及瓦斯解吸数据,指出可采煤层显微煤岩类型以微镜惰煤为主,煤化程度符合深成变质作用的一般规律,煤体结构以原生结构煤为主,可采煤层均为富甲烷煤层。

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.
